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.
