1997 GMC K1500 fuel pump and sending unit replacement

[speedygonzales]

Most electrical parts should be ONLY OEM. The fuel pump is one of them. I never saw a cheap auto store pump last very long.

For others, don't change the pump only for a couple of reasons. One, the fuel level sensor is a wear item and should be replaced when ever the pump needs changed. Length of time not withstanding.

Two, there is a check ball in the sending unit that prevents fuel from draining back to the tank, causing long cranking time among others. If you only change the pump and not the sending unit, you chance having to go back in because of a sticking check ball.
