I was going to try changing out the spring on my AD to see if I can get it up to abouy 15-20 psi. --- Update to the previous post... I changed out the spring in my AirDog.. Pressure is now 23-25 psi and it seems happier, although I didn't have a chance to "get on it".

I have the original Airdog 100 on my truck feeding my CP3 (with Arson III kit). I only see about 8 psi on my guage. I'm new to Cummins engines and am not sure the ideal pressure for the CP3..

Not sure you can just replace the banjos bolt, that fuel line coming off the prv is part of the return system

Well I borrowed a good working PRV and installed it. Truck seems to be happy again, back up in the mid 20's on rail pressure again

I just went and hooked up Smarty.. No codes present (at least that are related to rail pressure).

I can still pull codes, just no ses light.

Oh yes, I forgot my sig!I have a 2002 Ford F350. I just put in a 2004 5.9 CR that I rebuilt. I have 100hp injectors, arson cp3 kit, 63mm turbo and an airdog. Motor has about 1500 miles so far.I did just take the banjo bolt off the PRV and there is diesel in it.

Been noticing i cannot hold rail pressure. Yesterday while driving to seattle, my RP was only about 7000 psi @ 75 mph. Couldn't get much over 12k under heavy acceleration. I stopped to fuel up and after starting it back up, my pressures were better but still down. Thinking I popped my PRV, any thought?

This one had that too (under the battery ).

Anybody know if a tps from an '05 (the tps is part of the accelerator pedal) will work on an '04 manual trans truck?
