Does anyone know how much fuel pressure a P Pump motor should have.

 

to the injection pump or to the injectors?

 

------------------------------------
When my 1996 Dodge CTD was more stock than it is now, my fuel pressure would always stay between 22-28lbs. It should not go below 20lbs.

With the FASS 180GPH pump I have now with -8 lines running from my tank all the way to the P-7100 Pump I now see a pretty constant 40lbs. and it fluctuates very little.

Hope that helps you some.

A min of 25-30 for a stock motor with a stock piston pump.. 35-40 with mods and a better Lp

 

To the inj pump was what I was asking. Thanks for the help guys
