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. The fuel pressure regulator fitting in the upper portion of the module will have an O-ring on it.
6) Remove the O-ring from the end of the fuel pump hose or the top of the filter. Save this O-ring as it will be re-used later on. 7) Remove the connector from the end of the stock fuel pump wires. 8) Cut the new supplied fuel pump harness wires to 6” total length. 9) Strip the ends of the new fuel pump harness wires. 10) Crimp the Metri Pak terminals onto the new fuel pump harness wires. 11) Assemble the new fuel pump wires into the connector that was removed from the old fuel pump wires.
12) Slide one of the Oetiker clamps over one end of the supplied fuel hose. Install the hose onto the fuel pump outlet. Crimp the clamp into position over the fuel pump outlet. 13) Slide the other Oetiker clamp over the other end of the fuel hose. Install the supplied fuel filter adapter fitting into the end of the hose. Crimp the clamp into position over the adapter fitting. 14) Plug the new fuel pump harness wires into the top of the fuel pump.
18) Lightly lubricate the stock O-ring removed in step 6 and install it onto the new fuel filter adapter fitting. 19) Install the new fuel pump assembly into the module by feeding the hose and wires up from the bottom through the pump mount in the module. 20) Lightly lubricate the O-ring on the bottomn of the fuel pressure regulator. 21) Clock the pump so that the sock can fold up inside the bucket. 22) Make sure the re-coil spring is positioned in the bucket.
24) Connect the fuel pump hose to the top of the fuel filter. 25) Connect the fuel pump harness connector to the top of the module. 26) Follow the GM service instructions for installing the fuel pump module back into the vehicle. Use the supplied replacement fuel pump module O-ring. Congratulations, you have completed the installation. This pump flows roughly 50 gph at 60 psi at 12 Vdc, 60 gph at 13.5 Vdc and 75 gph at 16 Vdc.
