20) Snap the new wires with the crimped on terminals into the factory
white bulkhead connector, making sure they are fully seated.
21) Insert the black plastic end of the fuel pump adapter harness into the
fuel pump.
22) Reconnect the white bulkhead connector to the mating connector on
the top of the fuel pump module.
23) Follow the GM service instructions to reinstall the fuel pump
module, using the supplied replacement fuel sender module O-ring
(GM part # 22682111).
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. Some
of this flow is used to run the jet pump (venturi pump) that fills the fuel pump “bucket” or canister.
Without voltage boosting, this should be enough fuel flow to support roughly 650 to 700 hp naturally
aspirated and 550 to 650 hp in turbocharged/supercharged applications. For boosted applications above
650 hp and naturally aspirated applications above 700 hp, we recommend voltage boosting the pump
to 16 or 17 volts with a Boost-A-Pump. At high fuel flow rates it may be possible to empty the module
(“bucket”) faster than the jet pump can fill the module so make sure you do not run low fuel levels when
running at high power levels.
