Fuel pump Guru?
Post by vrod02 on Nov 26, 2006, 4:55pm

So I'm having interm. fuel pump issues. If it sits I have to prime it through the carb and then runs fine.This just started yesterday. Vacuum leak possibly? I was inside the engine compartment replacing my Heater core for the last time. Lots of fittings going to the pump.Thoght I might have bumped something loose but looks ok.Whos got em?

If you're running the stock engine driven pump you can get a rebuild kit from http://www.then-now.com. I'm at work so I don't know the part number or the contact info off hand... I think the kit ran like 40 bucks.

Simple fix.

It reads like a fuel pump issue. But, these things had a "sock" type filter on the in tank pick up tube. Old gas sitting for decades makes them clog up. Try blowing some air from the fuel line on the drivers side frame rail back into the tank with the gas cap off. There is a rubber hose there that is easy to pull off is why I suggest that spot. At the pump is just as easy. Of course, that hose I mentioned could be cracked and not allowing your pump to make any vacuum in the line.

You probably have the right diagnosis, but thought I should mention some problems many other have had in the past.

Barrman, I appreciate the comment.I'd rather try that than be a parts replacer. Nothing worse IMO So I need to look at vacuum lines as well right?

No need to look at the vacum lines unless your wipers don't work. Have you tried them to see? The pump also runs them.

Also make sure your fuel tank has at least 5 gal of fresh fuel. The gauge might be broke. You can also try a small can of gas under the truck and connected to the fuel pump with a short line to see if all is working well. Its just a matter of testing time, working your way back to the fuel supply. It sucks, ( well in this case it might not.lol.) but step by step work your way back to the tank.
Good luck, and let us know please what you find.
