I've figured out that I need a new fuel pump. Great fun to replace. I replaced it about 20k ago, but it won't hold pressure. I've checked into pump prices, and can get one for as low as $53 and as high as $77 for an AC delco pump. I believe I used an AC Delco last time, but it sure didn't last long. Does anyone have a recomendation on which brand of fuel pump to buy? I don't mind spending the extra $20 on the AC delco, I just mind pulling the tank out every couple of years.

 

Try to buy a Welbro off of Ebay or find a vendor for them. That's what GM runs on all there newer vehicles.

 

I wasn't able to get a walbro pump locally, so I went with the one for a Syclone. Supposed to be 44 gph verses the stock 24 gph. Same price for stock or the syclone pump. Now my pressure was still at 46 psi after around 10 hours with the engine off. I also elimated the pulsator and replaced it with the high pressure hose that came with the pump. So seems like I have that problem cured. Now on to the next problem.
