Factory original fuel tank fuel pump konking out on me...Have researched & read about their short lifespan from the factory, due to defective wire connections at the pump, that eventually make the pumps go bad. Should I replace it with simply a new stock replacement...such as a Carter brand...or is there a better quality alternative? Or.....should I forget the factory in-tank set-up, and go with an in-line aftermarket pump mounted to the frame rail? Thanks for any insight you might have.
Yeah, I ran into that myself in my 97 Astro van. The GM design on the drop-in-tank fuel pump/level sender assembly is prone to shorting out. I was going to replace only the pump with a Walbro in the assembly until I saw the connectors were fried. Due to the fried connectors I didn't have much of a choice but to buy a redesigned model from Orielly's at about $200 for the assembly. I think the brand was TexAir.
Crap, I forgot it was $279.99 for the pump. I usually remember when I get raped for a part. :cry:
Put the factory pump back in it. Put ACDelco part # EP381 it's $91.00 and it's just the pump, hoses and O-rings. This is what I did when mine went out. Be careful with the fuel level sensor, you can damage the reostat. and then you'll have to buy the whole assembly.
O.K., will do...Thanks guys. Have read that I also need to redo the wires & connections while I'm in there doing surgery. Oh boy, can't wait to do this job...wires and gasoline! I think I'll do this one in the driveway!LOL :eek: Thanks, Gar
Update: Just for shits & grins, I replaced the factory fuel pump relay in the power center, in the engine compartment. Guess what? It worked! Have been using the truck for a couple days now. So far, so good. Wonder if the wires on the fuel pump though, that corrode & are causing the pumps to eventually go bad, are also causing the relay to fail? Hmmmm.....
what year did chevy switch the fuel pump to 55psi? i know the ep381 will work, but when i go to autozone they want year make model.
1996 was the first year for the pick-up trucks. Tahoes, Suburbans, etc,. I believe were a couple years later. The complete 1999 line had high pressure efi engines/fuel pumps.
