We didn't get the pump ground hooked up properly after we disconnected the ground for the tank filler neck. Cleaned up the frame and the connector and has ran fine since, knock on wood.
What makes the AC Delco pump so much better than an Airtex? Both had a one year warranty. I probably would have bought the AC Delco if they would have had it but wanted to get the truck running. Guess if the Airtex craps out we can get the bed off pretty fast and we put anti-seize on the bed bolts so we can get the bed off in 15 minutes.

The reason airtex pumps are bad is the reports received on failures which occur 3-6 months after install..many on the forums have reported this Issue. not easy job and a PITA when this part fails.
ac delco or delphi have been reported to work good.
so what fuel pressures do you get now ? good luck ..

it is true that even an ac delco product can be defective with the way quality is in todays world.

Ever since we got the pump ground hooked up properly the truck has ran fine, knock on wood. Had fuel pressure of around 50 psi. I have drove it about 150 miles so far. If the Airtex pump craps out on me some time I'll be sure to update the thread. Thanks for the help and advice. Wish I would have discovered this forum when I still had my 95 Sierra.

the fuel pressure need be 53 psi or more engine on. with a new pump I would expect 56-57 psi.
key on engine off the pressure should be 60-65 psi.
if the gauge is accurate 50 psi will cause the engine to run but your on the edge.. good luck.
