1997 GMC K1500 fuel pump and sending unit replacement

[95 S_Trucker]

Your 98 should have a big plastic sending unit/pump assembly with quick connect nylon fuel line ends. 97 was the last year for the metal sending unit with line nuts where you can replace just the pump.

The pump for your truck will look a lot different than the one pictured in this thread.



Edit: Your replacemt pump will also come with a new connector. You will have to cut off your old one and hook up the old one. If you get Delphi or ac delco, the butt connectors with built in heat shrink are ok to use. You can also solder and use heat shrink tubing to seal the splice from the elements. Don’t use standard butt connectors or rely on tape alone to seal the splice.
