LOW Fuel Pressure With Your

AIR DOG AND FASS PUMP?

INCREASE YOUR HORSE POWER AND FUEL PRESSURE

WITH YOUR HOT P7100 CUMMINS

* OFV040HP Use with street performance Cummins trucks.

* Fuel pressure range of 30 to 37 PSI.

* Raises fuel pressure at full power.

The OFV040HP solves low fuel pressure at wide open throttle on your lightly modified Cummins Dodge Diesel Truck.

It has the largest oriface for street use of your truck that use and Air Dog® or Fass® pump.

Do not use this high performance valve on a stock fuel system! It is intended for use on P pump trucks only that use Fass® or Air Dog® performance fuel pump only.

Yes it can be used for P pump conversions on the 24V Cummins.

What fuel pressure should you be running? Here is a general rule to determine the fuel pressure you should be at. Multiply the governor spring rpm (in thousands) times 10. In other words, you want 10 PSI of fuel pressure per 1000 RPM of govenor speed. If you installed a 3K govenor kit, you need a minimum of 30 PSI at full power.  A 4K kit requires 40 PSI at WOT. 5K equals 50 PSI. Remember, this is at full power, not idle or cruise.

Do not use the HP valve on a stock fuel system! This valve will raise pressure spikes to the point that the stock fuel filter canister will blow a seal. The valve is intended for Cummins P7100 trucks using a FASS, Air Dog or high volume, performance fuel pump only.
