Replacing the fuel pump in a 1978 Jeep Cherokee: An Informal How-To

In this episode, I attempt to replace the faulty fuel pump in my 1978 Jeep Cherokee.

Hey Drew, here's something important for you about your Jeep: When I bought my '79 Jeep Wagoneer (same basic truck as yours) it had all kinds of problems including fuel issues, what I found was the previous owners had never replaced the original fuel filter which is attached to the drivers side frame rail about 12 to 18 inches ahead of the gas tank. In fact they had simply added another fuel filter ahead of it, and then another. That's right, THREE fuel filters, all of them clogged PLUS the fuel filter up close to the carburetor, that will cause the rubber diaphragm in a mechanical fuel pump to die very quickly. So I removed the frame rail filters and replaced them with the proper canister fuel filter then replaced the pump because it was shot, then I installed another filter close to the carburetor, the idea is to filter the fuel BEFORE it gets to the pump to protect it, then the second filter between the pump and carburetor keeps any residual crap out of the carb. So the only filter that should ever need changing is the one between the gas tank and the fuel pump. You'll want to check on yours before you go much further. BTW, this arrangement of fuel filters is is how I have all my carbureted cars set up. Great videos, keep up the good work. Mike '79 Wagoneer '67 Plymouth Fury 2000 RAV4

I’m looking for instruction how to install the fuel pump and said they can properly so I can align it if you just have a video about talking about needing to replace a fuel pump that’s not instruction it’s just a conversation you installed it didn’t show anybody how to do anything I mean you’re nice and articulate and well edited program I think you could do more about the installation process

Agreed. I understand that some spots are hard to get a camera in to film, but it would have been much more helpful if Drew had brought the camera over more throughout the process to show how things looked as he was doing it.

I recently bought a '77 J-10 that had the same exact issue. Replaced mechanical fuel pump and it started right up for me. I'm now working on restoring the rest of the truck starting with the fuel tank. Tank is good. I'm replacing all the old fuel hard lines with aluminum.

what’s the progress man, i got a 78 j-10 my brother never restored and i’m working on engine problems right now. would be helpful if you had any tips

[@groberts1980]

After flushing out any bad fuel, which fouled the spark plugs, and replacing the spark plugs, the engine runs great. It's the transmission I'm having issues with. It doesn't want to shift. I'm kind of stuck right now, I need to get the truck to a transmission shop. @@JellyBear-gw9uz

2.2 minutes into your video and I have to say that cam driven fuel pumps are famous for the cam lobe wearing down so instead of getting a new cam, just buy an electric fuel pump and presto. I'll have to watch the rest to see how it all ends up for you lol. Good luck 😋 edit* I had a 76 cj5 that I thought the fuel pump went out on and I had to just put an electric pump on it to keep from having to put in a new cam. Worked great!! Edit* again lol. I'm at 6.41 and I'm putting my money on a worn cam lobe 😏 edit* again again muuhaa lol, 8.08, I guess I'd have lost that bet lol. Glad you gotter running!! Good looking jeep btw, I was looking at other stuff on wagoneers and saw your cherokee and figured I'd watch it just cause it looks good 😋. I have an 89 and a 89 wagoneer I just bought so that's all iv been doing is watching wagoneer vids for a month now haha. Drive safely out there brother..
