I got a motor out of a newer caprice and put a pump on block... it never pumped fuel....

@@51-FS Most likely had the wrong arm on it.

Nope... cam didn't have the lobe....

​@@51-FS was it a 1996 model or something from the 80/70s?

90s. Efi center bolt valve covers. It had a place in the block for a pump but it was originally blocked off

I never had it happen but I’ve been hearing more people having this issue recently. The low quality of new parts can’t be helping anything either.

My dad had a jeep Cherokee some time back, safe to say it wasn't built for the Norwegian coast life, thing damn near fell apart everytime we hit a bump in it

No such thing as truck vs car pumps ... Sorry it doesn't work that way...

Fuel pumps don't have sumps. Also I've never heard of a car or truck pump being different.

The housing is nicknamed the "sump". If you check the parts catalog ( napa, Rock Auto, what ever you use ), look up a 1975 K5 Blazer 350. Then look up a 1975 Nova 350. You will notice that the blazer lists both short and deep sump fuel pumps. The Nova doesn't list the deep sump one, because of frame clearance. Hence the difference, between a car and truck fuel pump.

Your old pump was just week.... it would of did the same thing if u got a short pump

They're really convenient if properly installed. I mostly use them in a "hybrid" combo, basically for priming the system to save the starter some effort, and once engine es running, the mechanical pump takes the spot

Completely agree. Hybrid system is my favorite. I can’t stand the sound of the electric pumps especially the high volume ones almost as much as I can’t stand the nagging from my family and gf about how I need to scrap my 68 chev and buy a Honda cervix or whatever neutered clown car they want me in when they hear my old car crank for more than 0.000001 of a second before it starts.

Thats not entirely accurate. Please re-read what you wrote towards end.

Lmao cam should not wear out. If your cam wears out then I think your whole engine is done for lol.

One lobe wears off and the cam won't run the fuel pump.Lmas off😅

​@@ottoalseely3609 lmao what

An electric fuel pump took care of vapor lock issues on my 6volt flathead F3

They may vapor lock in the summer but at 40 below you pump the crap out it and it will turn over slowly but start right up. There were many days no cars would start but my 50 E1 would fire right up no problem.

@@domineech my pickup is like that. We had a winter in the early 1980’s when it was -60 with windchill, truck just didn’t care. Fired up and ran just like always.

@@markk3652 mine was in the late 80s and I was underneath it replacing the master cylinder at 50 below then the next 2 days was a water pump each day dripping antifreeze down my sleeves. It was outside too. Once I got that fixed it never failed to start.

I've had way more inline electric pumps go bad than any of my mechanical pumps, I actually went back to the original 50 year old mechanical pump on my 68 Impala after having said issues. It starts great even without a choke and if I hadn't rolled it I'd be driving it now.

I've always wondered if you could feed the electric pump into the mechanical pump and use it as a regulator

Not all electric pumps need a regulator

i like mechanical things too, the only thing i dislike about the stock pumps is that they tend to leak fuel into the engine oil after a while, might be hard to tell soon enough if the pump flows more fuel than your engine needs, i did a long trip in my 1979 toyota corolla once, the fuel economy was terrible, when i filled up the second time i checked the oil, it was black and a litre overfull (had just changed it before the trip) stank like fuel. so i had to ghetto an electric pump on, bypass the stock one and change the oil again to avoid engine damage from diluted oil, i think it did some damage already as the oil pressure isnt quite as good as it was before. but in any case, 10 years and another 100,000k later shes still running, dont drive her much, but its always in the back of my mind when i do

Doesn't really matter, I've been running a cheap Chinese fuel pump like this for two years with no issues.

​@@myadhdSquirelI has a holy pump under the hood of my 86 suburban.... worked just fine for the years I had it

We did on this car videos is on page we fixed this whole car, and it came out awesome . Thanks for watching

My 70 El Co fuel pump went out today. I guess I gotta order one online. I dont trust auto zone.

He lives near me. Cool dude.

Crap wiring bad mounting done correctly there just fine

I would agree with that I have one of those myself properly mount the pump and your good to go

I hope you installed it correctly near the fuel tank and not next to the exhaust manifold

@@JefeInquisidorGOW it’s right in front of the fuel tank. Remember, they blow, they don’t suck

@@jetmr_5043 nice

I had an 83 Fox Body I replaced the motor in. Old 302 had a mechanical pump. The replacement motor was out of a Thunderbird and was EFI. I swapped out the EFI intake manifold for my older carbed Weiand one. Didn't want to go through the trouble of converting the timing cover or replacing the camshaft. (The new motor had roller lifters and rockers so that was a plus. I just had to swap the drive gear on my vaccum advanced distributor. The new roller cam needed to mate with a bronze distributor gear. Otherwise the old steel one would have chewed up the teeth on the new cam.) After all that I just needed a low psi electric fuel pump for carburetor use. Got a good deal on one of the Holley Reds. Mounted it close to the tank and utilized the existing fuel line. It was wired up to a relay, which in turn was connected to a master switch on the dash. Did it this way as the car already had a bank of switches for the stereo and amp and whatnot. Plus it also allowed me to be in control of the fuel supply if I ever had a stuck throttle or whatever. A decent amount of work was involved for the whole conversion. But it gave me some good mechanical experience for only being 17 at the time. And you can't put a price on that.

I had a roller fuel pump push rod in an engine (SBC) back in the late 90’s. They exist.

I would agree with that 👍

Yes, but it's a different type of pump. Usually those mechanical pumps are a diaphragm type pump which can pull fluids unlike centrifugal pumps which I think is what that one in the video is. Peristaltic pumps are another type of pump that can be used as a 'lift pump' or one that can effectively suck fluid from a lower elevation

​@@davidjolly5218 bolth the mechanical and electrical fuel pumps are diafram pumps. Centrifugal pumps need to be primed to pump and are generally in tank only units. Personally I prefer to replace the mechanical fuel pumps with electrical fuel pumps. If a gasket leaks it's not going to flood my oil with gasoline.

@@putinslittlehacker4793 I think those external inline fuel pumps, like the one shown in the video, are actually rotor vane type pumps. But you're right that rotary vane and diaphragm pumps are both positive displacement types that probably have similar lifting capabilities. I guess that's why mechanical pumps are mounted so low on the engine block so that it is basically as low as the fuel tank to give that net positive suction head at the pump inlet

​@@davidjolly5218 not too sure about american cars, but older japanese cars (nissan and toyota) tend to gravity feed the diaphragm pump on the engine, always gotta keep a 12mm bolt handy if the tank is above 1/8th as when you disconnect the hose the fuel just keeps flowing 😂 its good, means when you grab your beast thats been sitting for 20+ years in a field or shed, you can flush the stale fuel from the tank real easy from the engine bay, and prime the fuel pump at the same time. are carb'd american cars set up this way too?

@@Colt45hatchback ahh, I think you are right. American carb'd cars are the same as long as you keep the mechanical fuel pump setup. I have a '65 mustang, and I do recall having to block off the fuel inlet hose to the pump when I had to disconnect it or else it would just keep draining.

That's a good point. Sometimes you have to get by this was not that

Vaseline will hold the push rod in place.
