Fuel pump under my engine is running, but fuel pump in tank is not working. Why is there two pumps and what do I do to fix my problem?:confused: I assume I need a new pump but is there anything else? What are the two censors on the air box?:faint:

There are two pumps on the 1000 sdi. The one under the engine is a low pressure pump that fills a resivoir where the high pressue pump is contained. This pump supplies fuel to the injectors. If the tank mounted pump doesn't work check the wiring and do a voltage test at the pump. If you have power at the pump replace it. It's common for either pump to fail. I have replaced several. Hope this helps you.

dont remember the part numb but gm basically only makes two pumps one for a throttle boby lp 15-20psi and one for a direct injection (vortec) truck 96-98 5.7l which puts out 60-65 running pressure dead head pressure exceeds 80psi so pump has enough psi and since it goes through factory fuel regulator should be good and only 114 my cost from lordco
