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. This O-ring
should remain in place and we be re-
used during assembly of the module.
4) Disconnect the fuel pump hose from
the top of the fuel filter. Be careful not
to bend the tangs more than necessary.
5) Remove the stock fuel pump assembly
from the module.
