If you have a high mileage vehicle, we recommend changing the fuel filters inside the module. The primary fuel filter and the inlet filter sock are not currently available as service parts from GM so changing these filters requires purchasing an all new fuel pump module. Complete fuel pump modules are available from LPE (see part number listed above).
Installation Instructions:
1) Follow the GM service instructions for removing the fuel pump module from your vehicle. Service manuals are available from Helm Inc. ( http://www.helminc.com ).
2) Unplug all the wires from the bulkhead connector at the top of the module.
3) Carefully remove the outer “bucket” from the fuel pump module assembly.
4) Using a small pocket screwdriver, carefully pry the fuel sock (fuel pump inlet filter) from the center pin on the bottom of the fuel pump. Save the fuel sock. You will be reusing the fuel sock when you reassemble the module.
5) Using wire cutters, clip the small ground wire as close to the fuel pump terminal as possible.
