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.

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.
