Not enough fuel, what to do?

[CL2000]

I have a p-pumped 24v and I have the A1SPBD003 kit (fp150). I have had a few different springs in it since I got it and its never been enough it will drop to 15psi and the injection pump radles.Can I add a raptor for a pusher pump or after the airdog? or should I step up to a bigger pump. What do you recomend?

Thanks,
Chad

dumb question, does it have the 1/2 inch fuel lines?

Yep half from the draw straw to the injection pump

dont hold me to it IIRC I remember see a thread by Dalpilot I belive where he ran a airdog into a raptor with no problems. Here is the thread that he started. AIrDog, and Raptor installed - Competition Diesel.Com - Bringing The BEST Together

15psi not enough? :what:

 

[Mr.T]

my AD 150 keeps my fuel pressure about 25psi at WFO and i have a tuned 230 P-pump, so something isn't right

My raptor will make 60-70psi at idle and 30+ at wide open. I got a 65lb spring from pureflow for $5.75. All is good now.

If you were messing around on the pump and had it apart, then put it back together and put the cover/plate over the pump gear the wrong direction it will not move fuel like it should.

I never had the pump apart only the fitting out where the spring is. 15psi isn't enough.
