I don't mind losing customers, but i do mind losing GOOD customers. No loss here.

Although the customer was close minded, take solace in the fact that you taught me to never overfill my fuel tank.

It's very easy to diagnose a simple problem when all the time consuming,preliminary work is done. Great job Rainman

Ray, early on you spotted the problem by looking at the fuel gauge. But you went through the entire process to confirm the hypothesis. Great job. Maybe he's just embarrassed, and he'll learn to stop overfilling his tank.

It's unfortunate that the customer was unwilling to listen, though on the other hand you've taught all of us a valuable lesson for why we should never overfill tanks.

Wow! That was a heck of a thorough, well-thought-out, troubleshooting chain of events ! The only thing you can't fix is stupid! Outstandingly good job!

I overfilled my tank once and it started chain of events that ended up costing me a lot of money. I learned that lesson the hard way.

Normally these type of people are "KNOW ALLS" that never have achieved anything in life except riding on opportunities. You on the other hand have gone out of your way to lay the proof on the table. You are a thorough GENTLEMAN concerning your situation. Well done, you are the winner.

The hardest part of being a mechanic/technician is the customers. Lol

I feel your frustration, Ray. When you pour your heart and soul into your work, you open yourself up to mindless jerks who think nothing of crushing spirits in order to further their own ends. In this case, the customer couldn't believe that he'd made a mistake. Rather than laughing it off and learning from the experience, he kicks the first dog he sees; unfortunately, that was you. I've learned so much from your videos, and you've become a vital part of my morning routine. You have the perfect combination of technical acumen, personality, and humor that guarantees success. I hope you can shrug this off and understand that there are some real dirt bags in this world that simply can't be pleased and don't deserve another moment of your time. Goosfraba, brother.

The uncut zip ties are for trimming weeds on the side of the road!

Dude, nice work. That was some serious diagnosing skill. I'm glad I sat through and saw your decision making.

My dad had a motto that he always followed. Sometimes, you have to fire a customer. Should not happen often, but every once in a while, you get one that just isn't worth keeping.

Another masterclass in diagnostics, well done sir! Re: the disgruntled customer; Always remember "No good deed goes unpunished." Don't take it personally. We love ya!

Since this OG was a teen I have had many jobs that required interacting w the public. From being a stock boy at a neighbor's pharmacy to my last 26 years as a Psychiatric RN. I learned many lessons in my working years. When one develops expertise in a particular area allowing that expertise to, "speak for itself", is often the 1st line of defense in dealing w difficult, unreasonable & those who go so far as to question a person's motive. I'm not a gear head. I have rudimentary automotive knowledge. I cannot help but be impressed by your plain speaking, everyman approach to problem solving. The way you work & present problems keeps me instantly invested in watching. You draw me into a journey of diagnosis, challenge logic, discovery & solution. Well thought, thorough, honest, consumer advocate w accrued expertise & seemingly humble as well. You are a credit to your profession.👍🏼

You have waaaay more patience and professionalism than I am capable of in such a situation. Props on keeping your cool

You might want to send a letter to his mailing address in the hopes his family reads what's going on. Grandpa escaped in the Camry again and he's been trying to fix that same gas vent since 2011. He makes sure to let everyone know each year on the Christmas cards he sends out to overfill their gas tanks. "If it doesn't click 8 times, Grandpa isn't proud of you." Ray you've disrupted a long family tradition.

Brilliant diagnosis; so well done to you. We can please most people most of the time but cannot please all people all of the time. The customer is not always right. Thanks for sharing.

I remember learning about the EVAP system in school but did not fully understand the system, but this is a perfect example of diagnostic to the system. Thank you!!!

For sure I tried to round out my fuel cost to an even number. Click, click and another click. While this customer did not appreciate it your viewers did. I for one learned a valuable lesson and no longer try to overfill

I was expecting that kind of a response from the customer, having all these parts replaced previously and not saying anything about it, he just needed a confirmed repair as a second opinion, made all the fuss just to not pay for your work and diagnosis, and he got what he wanted and got away with it, great work Ray, as usual.

Some owners just don’t take responsibility for there actions, they just don’t believe it could possibly of been them that broke their car, Unbelievable ! Thanks for another great video Ray

Back in the day, before all the smog stuff, we used to start the engine and then use an unlit propane torch to run the nozzle over all the possible places a vacuum leak could happen. If there was one, the engine would rev up a bit as the vacuum sucked in the propane gas. Worked flawlessly every time we used it.

I wish I could find a mechanic in my area like you. You are well trained, thorough and honest. Great video!

A sign of the times. Nobody wants to accept responsibility for their own actions, even when presented with the evidence. It's much easier to blame somebody else.

As my dear departed father used to say, "There is an ASS for every seat"!!! This profound statement is the result of our family owning an autobody repair shop for 64 years and dealing with a wide range of Humanoids that would wonder into our shop. Some customers have nothing between their ears and are just Jerks! As always, GREAT JOB RAY!

Former autozone employee here. Thank you for the videos. So often people would come in and have us run our simple diagnostic tools for them and when it came up with an EVAP leak most of the time we would just sell them a new gas cap. Please tell people that autozone workers are NOT mechanics. Sure we might have some knowledge ... but that is not what they are there for. Autozone workers are there to sell parts. That's it. Sell parts. Everything else they do is EXTRA that you should be thankful for. And if that autozone employee goes the extra mile for you ... TIP them OUTSIDE .. and insist on it. They are told to refuse tips. But I can assure you they would like it and it will encourage continued better service at that location. If an autozone employee says that they don't know how to do something ... BELIEVE THEM.

“Just because it’s new doesn’t mean it’s good”. ~Eric from New York. 🤗

This is there should be an intelligence test before being allowed to earn a driver's license. Great diagnostics, as always.

Note to self: overfilling the gas tank is worse than I thought! It's great to learn new things from you Ray. Once again, a thorough and fantastic diag that will be useful to me someday.

The minute I saw they had a brand new canister and vent valve I had my suspicions. I’ve run into this a couple of times. Typically I’ve found that the over flow/vent line to the tank has been particularly or completely clogged so the gasoline backs up into the canister before it should, while filling up.

You did a great job diagnosing the vehicle. Mechanics, dealerships, and owner's manuals state do not overfill gas tank or words to that effect. Great job.

This man owes you for diagnostic work. Unless he turns around and sincerely apologizes, I don't think you want him as a customer. He will just waste your time.

I've always heard that you should not over fill the gas tank, now I've seen visual proof that over filling is bad for the car. Good video!

It's amazing that the customer didn't know what was wrong with the car. Hence, it showed up in your possession to diagnose the car, you diagnose the problem, and tell him the diagnosing procedure and what causing the failure and immediately he became the expert and said you were wrong. Ray one thing you can't fix is ignorance or stupidity 🙅

Car is in surprisingly good shape and CLEAN too. Remember you ran the first test with a full tank. Not recommended.

Click bait "you're fired"? Your videos are awesome, no need for hyped titles to get us to watch, im subscribed and I still think you're a mechanical genius!🍺👍

When someone doesn't know what is wrong with their car, takes it to an experienced expert, then doesn't want to listen to the well performed comprehensive diagnosis of the issue because it was user error.... 😖😖😖

I was today years old when I found out you could overfill the fuel tank! Thanks for that!

So hard to try to help people out like this who don’t want to believe their actions were what caused the issue in the first place… your work speaks for itself and even though I just watch your videos as a young mechanic the way you go about diagnostics truly helps me figure out where to start and what to check. I’ve learned a lot over the years from guys like you who are genuine and honest mechanics.

Let's not forget that the tank is full. The scan tool did say tank should be 1/2 to 3/4 full for diagnostics. For all we know, evap may still work once fuel gets down to optimal level for evap.

Could be a plot to test your skills? You passed , good job !

I use to fill to top of tank . Never knew you could destroy a part doing that haven't done it in 35 yrs . And thanks to you will never do it again.never going over full . Again . Thanks for the heads-up 👍

I paused at 8:30 to guess/comment before continuing: I would detach the evap canister first to check if it's filled with gas. I sometimes see this happen when people habitually overfill their fuel tank. And now back to our regularly scheduled video...

Thanks Ray for your understanding with idiot customers. Most people have no clue. Hope the guy will learn something today by watching the vid.

The beauty part of the whole situation is the following: You can't be bothered by someone's insult if you don't care what they think. By dismissing your diagnosis, this customer has made it clear that his opinion isn't worth your time or your worry.

"I don't think that's wrong with my car. I used to be a mechanic, and...." "Did anyone ever tell you just how mind-blowingly brilliant you are?" "Well, actually....no." "They never will."

You are correct. Never top off the fuel tank!! When you do there is a good possibility you will flood that charcoal filter with fuel and the canister will no longer work. If this happens in dusty conditions it will turn into cement inside that filter. Been there seen that. I enjoy your videos. Keep up the good work.

Excellent work on the diagnosis. I've had customers throw full on temper tantrums when they find out the issue was caused by them. Nothing to do here except tell the customer you can't help them. Unfortunately, the customer will tell 1000 people how you tried to "rip them off". On the flip side, if you found something like the vent solenoid not plugged in, connected it, told them "no charge, have a great day", they'd never tell a soul. 😐

The customer may not have appreciated your hard work but we sure do. I’ve done an extra top up with the fuel myself but now seeing what it can do, I will never do it again. You have helped to reduce a needless repair, thanks Ray! =]

Can't tell you how many times I've filled my gas tank all the way up. Especially on long trips. Very glad I watched this video. You rock Ray! (Rocking Ray) ?

I made the mistake of overfilling gas tank on Honda Odyssey. My mechanic told me, "Don't do that!". So I quit. Problem solved, after I paid him to fix it. I realize most of you mechanics are looking out for us little guys, and I appreciate it. I'm a plumber, so I get a lot of the customer know it all headaches you guys do, and it ain't no fun, but the good customers make it all worthwhile.

Gees, I hope you got to charge him for the diagnosis. Being in the consultant business myself, all you can do is tell the client what the issue is and what the ramifications will be. What they decide to do with that information is their decision.

Ray , listening to your friend description yesterday, was an eye opener. Your drive and determination to make a good life for you and your family is outstanding. Overcoming the many obstacles in your way has provided me with more of an appreciation of you. Your pleasant outlook on life, your mechanical knowledge,/ablities, and strong work ethic, is exceptional. The world needs more Rays. If you get a chance, watch the video about Ray made by his friend. The video is very well done.

People don’t want to take accountability. Keep doing what you do!

I don't know the intricacies of how my car works, but there's something incredibly satisfying about watching a diagnostic work-through even though I don't know what's going on. I also learned something today. 20 minutes well spent

Once again. Exceptional work. Only the customer knows how many times he’s been told what you’ve found to be the problem and had the canister changed.

Hah! I remember sitting in a queue at Costco fuel, for the ultra high flow pump. Two cars ahead, a middle aged lady in a Prado, filled to the click, the pump handles are quite heavy on the high flow pumps, and the hoses visibly jump when they click. She then squeezed again, overflowing the tank, and spilling a liter of diesel out of the tank, onto the ground. As the nice Costco attendant set up her cones to clean up, the young bloke in front of me, in a Hilux, gestured in disgust, and I could see his grimace of annoyance in his mirrors. After 5 minutes cleaning, he pulls up to the pump and proceeds to do the exact same thing. 😂🤣

Great work in solving the issue, real perseverance & you have probably saved him more money & pain.

Great job diagnosing Ray!

I'd suggest a new transfer case and a blinker fluid flush

I did the same thing to my Chevy Colorado once. I didn't know any better. I was commuting 180 miles round trip 6 days a week. I would try to squeeze in as much fuel as I could so I wouldn't have to stop for gas that extra time every week. I went through 3 canisters before anyone clued me in. I felt so dumb when the mechanic explained it. I was really nice about it, though, and thanked him. So, I get where the guy is coming from but at the same time, you gotta take the education with humility. He was probably embarrassed and his natural reaction was to lash out. Good luck to em.

Sorry you had to work so hard for it to go that way. Whatever diagnosis you give, I would never doubt. Your truly an amazing mechanic!!!

Got to love people that bring you their cars to be repaired and then don't trust what you just told them, even my owner's manual tells me not to overfill the gas tank

Thanks to you Ray, I never knew you could hurt something over filling the tank! THANK YOU I'M GUILTY OF DOING THAT! AGAIN THANKS!

Nice thorough diagnostic work Ray. It’s always sad to hear that a customer isn’t willing to hear out the diag and do the repair as well as hear how to prevent it in the future. Hope they get it taken care of and stop overfilling their tank!

So many people have been ripped off by crooked and lousy mechanics I can understand the customers mind set. BUT you are doing everything right! In the end it's the customers loss!

Mad Diagnostic skills, thanks Ray for sharing

Thank you for this video Ray. After years of telling my wife that she shouldn't fill the tank past the first click, I now have video proof that I was right!

Human nature sheesh. In all my years I’ve only argued with a mechanic once. A small shop they evacuated my AC. They were supposed to charge it but they said it leaked. I paid. Took it to the dealer who tested it no leak, they charged the system it worked perfectly. Took the guy to the Bureau of automotive repair. Got my money back from the first guy. Cost me 100 bucks at the dealer. Otherwise I’ve had reputable mechanics. Kudos to you Ray you’re a cut above.

Wish I could bring my car to you! An honest knowledgeable/honest mechanic like yourself is great to see.

Toyota acronym for Vsv stands for vacuum Switching Valve @Rainman Ray's Repairs

you just taught me a lesson on over filling,never even knew it was a problem ,thanks .

Nice that you stuck to it even when ideas seemed exhausted. Congrats on finding it! Didn’t know that overfilling can lead to all those issues. Maybe guy will cool off and realize… what no one wants to hear, “what you are doing sir, is wrong”

I am so fascinated at how knowledgeable you are. I used to be a diesel mechanic back in the day. Dealing with those types of customers was so frustrating. Just watching your videos makes my day. Thanks for the great content!

Outstanding diagnostic tutorial thanks Ray.

With gas prices going so hi lately this will happen more often. All to save a few cents! When the pump clicks off, STOP FILLING!!! Nice job Ray!

So frustrating to see the obvious diagnosis but semi understandable in a way that the customer doesn't understand but that's why the fuel pump clicks off so that you do not overfill as it leaks down into the vapor lines

Thank you for adding the text slides. I think its a great addition.

Great diagnostic work. thanks for sharing.

Great video !! I'm one of those guys that always squeezed in another dollar or 2 of gas after the pump clicks off....but I won't anymore after seeing this video. Thanks Rainman 👍👍

I love videos that involve troubleshooting via electronics. It reminds me of trying to troubleshoot a motherboard in a computer to find a dead capacitor or broken trace.

That was some top level diagnostic work. From the ground up to the ridiculous reason why it happened. I tip my hat to you sir.

Like watching your work. Reminds me of when I was younger.

I seem to recall the warnings in the owner’s manuals on my (old) Toyotas and “new” Ford to NOT top off the fuel tank, with an explanation that exactly this result could happen. The gas pumps also warn “Do not top off fuel” on all the stations. Customer could have read that but did not or refused to accept it.

I have to admit, this is the first time I've heard that over filling the fuel tank can flood the charcoal canister and ruin it. Sure, I have seen the instructions to not over fill, but assumed that was just to prevent spills. And I am not in the habit of "topping up" the tank anyway... So have probably never made that mistake. But, hey, it's good to know and proves you can teach an old dog like me something new every now and then!

great effort ray fr... sometimes people cant be convinced

Your videos is very informing and taught me to make sure that I don’t accidentally overflow my tank and cause the same symptoms I’m glad you documented it up so that way if they try to say something later you have all the proof showing your diagnostics and you did more than most people would try to diagnose it so very informative video thank you

Self inflicted wound! This is a great video. Shows consumer ignorance and teaches how the evap system works. Great work Ray!!

I have got to say I know nowt about cars that are being made these days, Moggie's and Beetles was my time, the stuff that's on them now is mind boggleing, Ray I just enjoy going along with your repairs whatever it is, just keep them coming, thanks

Your diagnostic skills are next level. 👍👍🔥🔥

Me too. I knew nothing about over filling the tank. Thanks so much for that info.

On a management course I attended with a group of others, a psychologist asked us to write down the two best moments of our lives, and the two worst. We were then asked to remark on who was responsible for the 'best' moments. and who responsible for the 'worst'. Close to the end of the class, the summary we were presented with, is that "we" always claim responsibility for the best moments (like personal achievements), and the worst, always down to "someone else", even if we'd set up the situation prior to the disaster arriving. The conclusion then, is that bad things that happen to us, HAVE TO assigned to someone else. This is a great example of proof that condition exists. I've been working on and fixing computers for over 30 years. (386 + DOS days.) 6 months ago I got asked to sort out a fellas problem with a printer. He thought it would be a simple 2 minute job, which it wasn't, not least because of his peculiar setup. Anyhow, I got the same reaction experienced here. A fella who knows next to nothing about modern operating systems, telling me I was doing something wrong. Even if I had been, how was he to know? I was doing this as a favour, so the 15 minutes I spent on resolving the matter didn't cost him anything, but his pissy attitude will mean he won't be getting free help in the future. Seems I fixed the problem (I was told later), but I didn't get thanked for it either. Honestly, some people should come with 'health' warnings.

Great work Ray. Australia doesn’t have the stringent pollution rules you guys have but trickle filling the tank to max creates problems I never considered. Love your work and the vids. I’m learning heaps watching how you tackle your work. 🇦🇺👍

I really like your videos. Just came across them. I'm an auto body repair mechanic trying to start my own channel and run across all these issues. Please keep posting it helps our community of repair monkeys with your experience and techniques!!! Earned a solid subscriber

Good job Rainman!

I must say that on occasion, I am guilty of overfilling my gas tank like this. I have never experienced any issues arise from doing so but I now understand why it would be a good idea to never do it again. Thank you once again sir for your videos. And I hope the guy who owns this toyota eventually realizes you were right and maybe even comes back to apologize to you.

A friend of mine had the over filling issue I found out when I replaced a second charcoal canister I less than a year. He would click click & click again when filling the tank the second bad canister was full of raw liquid fuel, I explained why they call it a"vapor" canister. Good point.

Well, customers don't like to be told it was their "Whoopsi" that caused their problems. Good video on overfilling the gas tank.

I learned something new today about overfilling a gas tank.
