I posted in the towing section because that is the main duty of the truck.
1997 K3500
7.4l 4l80e
stock except Five O Motorsports injectors and Gibson short header and flowmaster 50 series
I keep burning fuel pumps. 500 to 1000 miles (roughly).
I bought the truck with a hole in the bed for pump replacement. Ground is clean at the pump to frame. New ground cable to block. New braided grounds from engine to frame to body.
Replacing with Delphi units. New filters. New socks. new FPR. Tank is not rusted/contaminated.
Any theories to what is happening?
