INITIAL START PROCEDURE
1. Turn the starter key to the on/run position.
Note: It may be necessary to bump the starter for the ECM to energize the Raptor™
FRRP-150 Fuel Pump.
2. While the Raptor™ FRRP-150 Fuel Pump is on, bleed the fuel line to the filter
canister by disconnecting the quick connect at the canister. As soon as the line is
purged of air and fuel is observed, quickly reinstall the female quick connect. A click
will be heard when properly installed.
3. Start engine!
Adjusting the Pressure Regulator
NOTE: PureFlow AirDog strongly recommends the use of a fuel pressure
gauge to monitor the output pressure on all of its fuel systems.
To adjust the fuel pressure, loosen the lock nut on the regulator adjustment screw. Using a flat
blade screw driver, rotate the adjustment screw clockwise to increase pressure or counter
clockwise to decrease pressure. Be careful not to loosen the regulator assembly base. If you do,
tighten it immediately. When finished, properly torque the regulator adjustment screw lock nut!
Properly tighten the adjustment screw Lock Nut when finished.
