Testimonial: "hello Jeff,..I had just recently removed the line from the fuel pump to the filter of the 1993 c-1500 with the 4.3 motor in it, short body truck. I had expected a greater pressure from the hose I had also removed the line from the line from the throttle body to the pump also expecting greater volumn and pressure at that point found minumal pressure and volumn. I then by-passed the fuel filter to the throttle body thinking possible plug of filter, though newer filter. NO START! with a primer..Just prior to this i had tested the relay all seems to be working as it should sending signal to the pump...I believe my pump loses prime and is not strong enuff to push up fuel to the throttle body fully, if at all in a sluggish manner. Ive decided to try another pump from my local salvage yard, my guy sends me most always good original parts for years now!..any thoughts? greatly appreciate your input,..thank you scott"
Obviously it is a fuel pump.Some gm's grounded through the tank,frame or harness.All are acceptable
