I spent 6 minutes of my life on this video and it was worth every second. I've learnt sooooo much in this short video. Thank you for taking the time and making this video. You would make an excellent teacher or trainer. Thanks again!

This dude should be at a UNIVERSITY teaching..he talks great n makes u understand every detail..God Bless you..

It's amazing how many things are working together in a car, and how complex things like a fuel pump are.

This guy knows how to make and edit a video. Many KZfaqr's can learn from him. Thanks, very interesting on the fuel pump.

Very good explanation. Recently the fuel pump in my car broke down, and I came here to understand how it all works. Thank you so much.

How anyone can give this video a "thumbs down" is beyond me. This video was incredibly detailed and more than what I expected. I am glad that I found this channel. It will certainly take my learning to a higher level. Great work!!!

If not the best explanation of a fuel pump I’d ever seen!

Learned more in that short video and had every question I had about fuel pumps answered within 7 minutes. I had been searching the internet for 2 weeks now and still didn’t find the answers to my questions. Found this video and BAM every question and things I didn’t know I was gonna ask eventually were answered. This guy rocks.

Awesome video. Great pacing, no bs at all

Driving for one year and never got to know there's even a motor in the fuel tank. This video makes me wonder how complex ICE cars are. Btw, this video is great. very much straightforward

My car's fuel pump is giving me problems so I'm here looking for videos and you explained every single piece of the fuel pump. Respect! Excelente video!

Just what I needed to learn: thank you! You saved me the trouble of taking my old one apart. My Astro's fuel filter is separate from the tank, and its pressure regulator is built into the carburetor. It thus requires a return line to the tank from the carburetor. It's amazing that my new pump can put out as much as 60 psi with just that simple impeller you showed us, that is, if the fuel is blocked from flowing by a pressure measuring gauge. I didn't measure the flow rate, but adjusting the constriction to flow is how the pressure is controlled.

This is how a great informational video is made. Good edits, no nonsense, not having to watch all 8 bolts being removed, just all pertinent information. Good job, thanks.

Hey fella just wanted to come back and thankyou for this video because it taught me that my GM Agila a uk vehicle fuel filter was in the fuel pump assembly and it was stuffed full of crap. I had done the usual that is changed the pump initially and no change until I saw your video. cant tell you how brilliant your video was for me. I bought a complete unit and tested it off the car like you did and the pressure went from 7psi to 55psi and I new I was on the right track. Most other videos only focus on the pump. yours showed it all and I am a definate follower for the duration. You are a star in my view. Thanks for helping me!! I dont however understand why manufacturers put fuel filter in the unit anyway. I always thought fuel filters were outside so that they could more easily be changed. Go figure ay!! I really like you style especially your big spanner LOL!!! keep them coming. are you in the trade? excellent!!

I'm just preparing to replace my fuel filter, didn't think I really wanted to get into the fuel pump / sending unit assembly at the moment but it's really quite simple and clever. Didn't realise the float and low petrol light were different mechanisms, I guess it's good to still have the dash light if your float circuitry fails for any reason. And it's just using the fuel as a conductor which disappears below a certain level, again so simple. I think we often get tricked into thinking things are really complex because the overall system is. It's great how you break these things down to make it more digestible.

best 6 minutes I've ever spent in KZfaq, straight to the point, in word's anyone can understand. thank you good sir

Nicely done video! I wish I knew as much about anything as you do about fuel pumps.

Great content as usual, your brother needs to keep an eye on his clothes hahahhaha

One of the most worthy 6 minutes on KZfaq.. Subscribed and highly recommend this channel. Respect from Pakistan 🇵🇰

This kind of video editing is reminiscent of old-school educational videos. Straight to the point and actually about the parts I wanna know.

Excellent - quick and to-the-point. Didn't leave anything alone - opened it all! Well narrated. Good job!

Great visuals, great editing, great video. No bullshit; just the bones of what we need to know. Brilliant.

Imagine if he forgot to press record. Impressive video by the way.

Ah-ha! That's why my low fuel light quit working several years back. The pump and fuel level sender continues to work so I ignore that problem. Great video. Good pace.

This video is so underrated. Amazing breakdown!

I get so much out of your videos. You could be a lecturer or teacher of anything. You are really smart! Thank you!

A lot of KZfaqrs can learn from you. Brilliant video.

I have been dissuaded from building my own fuel pump after watching this very well-made video.

Best educational video I've ever seen on KZfaq. Thanks!

Literally the best explanation video on anything I've ever seen. Well done. (not to mention funny!)

WOW! you sir really know how to break it down in teaching about how a fuel pump works!I I learned a lot more watching your video than I did watching 2 other videos before yours about fuel pumps!! Thanks!

That showed why its so important to never run out of fuel. The fuel going through the pump actually cools and lubricates the motor. Without it a fuel pump will overheat very quickly and that shortens its life.

CUT OPEN ALL THE THINGS! Another excellent video and your brothers sock made a surprise appearance.

So much technology and details in a fuel pump, it is a magnificent complex of ingenuity. The more he cuts to find details, the more I appreciate engineering.

Very good tutorial. All we do is sit and drive our vehicles. Without the fuel pump we are going no where.

Another awesome video! 🚗 Thank you! 😊

Dude! That was a fantastic explanation. Bien hecho!

3:38 interesting how the rotor has those rounded oval indentations. maybe for magnetic flux and/or possible fuel line contaminants.

Interesting about the fuel level sensor graduations. Thanks for the *excellent cuts and no stock music* and use of technical terms like series resistance. A+++

Can't thank you enough for your videos. Your detailed explanations are the best I have seen. May I ask where you acquired your knowledge? Did you attend university and obtain some sort of engineering degree? I have not seen anyone on KZfaq with the level of engineering knowledge that you have.

Very informative. Great video!

Note to self: The guy used a battery and some jumper leads to send power to the fuel sending unit after it was taken out of the car. This caused water to be circulated in a pan of water that he set the pump down into. So it doesn't have to be gasoline that moves within the pump, apparently it won't be damaged by water going through it and a 12 volt battery can power it. Also, it appears that the float and variable resistor combo does NOT tell the car if the tank is close to empty, it appears there is a separate sensor that does that. Note that the gasoline itself is what keeps the Direct Current motor inside of the fuel pump cool. There's also a pressure regulator, not only beside the throttle body injection unit, but one inside the fuel pump too. It's usually encased inside a large black plastic box and makes up the bulk of the fuel pump aside from that part which is mostly air inside the casing.

As someone who doesn't know a damn thing about car stuff, I find this fascinating and educational. Well done.

The fuel level sensor is a thermistor that stays cool when submerged so its resistance is high. When not submerged, it starts to get warm from the current and heat up. More and more current flows as it warms which allows the light on the dash to illuminate.

I'm working on a fuel pump tear-down video of my own; should be out within a month. The fuel pump I have is twice as tall, and I didn't have to use any power tools to get into the metal casing, so the inside will be a little cleaner. It's interesting how different the spinning element of the pump was between mine and yours.

Legend has it hes still cutting into the fuel pump. What a great video explained every single peice love it.

Im gonna replace the fuel filter for me car soon, this video really solved all my questions in my mind. I always thought that the small tea bag was the only fuel filter for the whole system, until I watch this video and you cut things out for us

This video makes me feel like a mechanic.

Why do the sparks generated by the brushes of the DC motor not ignite the fuel???

EXCELLENT EXCELLENT!!!!Yes very good, very educational, very easy to to follow and understand. Your video describes how a fuel pump works and breaks it down in steps and the individual mechanisms...EXCELLENT EXCELLENT!!!!!

awesome, blew up the water pump on my portable shower (4wd ing around Australia), so got a fuel pump from the wreckers and pulling apart to replace the motor.. Should get a bit more pressure out of it as well. Cheers.

So this is one of the best things on KZfaq I've ever seen, I learnt so much. I'll admit that initially I thought it was Donald Trump, my bad.

You are the best.

Packed with useful information. Tight, fast-paced but comprehensive. Doesn't miss a thing. Love this video. Thank you.

This guy is 4 years of automobile engineering degree in videos. I learn here much more than I do in college.

Good stuff.

yay the toothbrush is back!

I have that exact fuel pump assembly. Those were the easiest to work on;however you go above and beyond by slicing up the pump and showing us the guts.

Damn! This guy knows his shit. This is the type of self confidence I want to expect from my mechanic before and after dropping off my car...

Entry and exit of fuel got mixed up.

Dude has PhD in fuel pumps..

You make the best videos anywhere but man you are brave to do this without gloves

You are the best auto mechanic in the world. Thanks for the video sir.

Could the fuel filter be replaced with your brother's sock?

Give away Tooth brush at 1m subs !!

Excellent dissection of this device.

Very good demonstration. Excellent

This is how people should explain things Great work

Great video ! 👍

You answered everything in the text. Thanx again.love your videos

Thanks, very nice video to understand insights of a fuel pump. I found very valuable to see the pumping volume while working and also the working principle of the filter fuel bypass valve.

හොදම පැහැදිලි කිරිමක්, අනිවාරෙන් ඔයාගේ video නරඹනවා, superb, grate work, translate you my word, it sinhala

Hats off to you hardwork to explain all these stuff

Your channel is one of the best. We got chrisfix to show us how to replace parts and you to tell us HOW it works!

Brilliant - no fluff, to the point and very informative - Thank you!

Never seen a toothbrush used as a pointer before quite interesting..... Think the variable resistor is called a potentiometer....... Also before you take the pump out good idea to blow the top of the tank with compressed air before you remove it otherwise all the junk and dust and rust will drop into the clean fuel tank... Good video I like seeing things taken apart like that it’s very helpful and for the most part all the different models of car doesn’t matter the fuel pumps are essentially similar....

You guys are amazing. Short of breaking open the wire- damn you showed the system in detail. Great job.

This Fuel pump assembly is unique in that the pump, regulator, and filter are all combined into one unit. For example, my car has a fuel filter by the tank under the car, the regulator is by the engine block, and the pump is obviously in the tank. It seems like the video is saying that the pump has both a filter and a regulator but it usually doesn't.

Outstanding video! I'm showing this to my children so they understand why they shouldn't run their cars down to empty. LOL.

Very helpful video. I need to replace my fuel pump and this video made me understand a fuel pump and it’s parts a lot more.

The amount of technology that went into making this one piece of a car is mind blowing.

If I could like this video 100 times over I would, thank you for the video!

It couldn't be better!!! The best video ever!! Thank you very much!

It's a good time cause I have a project coming on this week to change my fuel filter,housing and the strainer on my car Thanks again for these valuable information

Very informative video , the fuel level low sensor I think is a heated resistor and ecu check the resistance change, when fuel is not touching the resistance it gets more heated and increasing the resistance indicate low fuel level.

this Video was a hidden Gem. Very good. Allot of info and 1st hand observations.

This explanation is wery good. Many thanks to you. Now I understand how remove fuel pump from the fuel filter. Today I removed fuel filter from fuel tank, but I don't understood how remove bad fuel pump from the fuel filter.

U know shit is serious when ur explaining with a toothbrush 💪

I won't leave without subscribing to your channel.

Quick explanations and dirty demonstrations. Love it!

This is the greatest KZfaq video I've ever seen! It's like Tesla and Bill Nye made a test tube baby with the two guys from Car Talk! Lol!

Awesome video. Hands down completely broken down to every single lil detail. Question my Frs only has 26k miles and the fuel pump just died on me. I'm confused to why would it give out at such low miles

This is so detailed. Thanks very much for the video.

Thank you ! Very explicit and straight to the subject video

I like that you get to the point, I think most people that post videos just like to hear themselves talk. Good Job!!!

Dude! You are the best! Toothbrush caught me off guard. but I dig it. Thank you for the explanation, keep 'em coming

Thanks a lot. Now I have it much more clear than I really needed. You are a real expert.

Best video and explanation are made easy... I feel like a graduate

nice breakdown
