I installed my arson III kit the other day and took it out for a drive and whenever you accelerated the fuel pressure would drop from 20psi to 0-5psi. took out the relief valve or whatever it is by the fuel inlet and replaced it with the stock one and it would hold 18psi wot.

any ideas?

THanks,

Which relief did you remove?? Rail valve or which??
 
The cascade valve that Shane puts in his kits increase internal pressure of the cp3 up to 140psi or so and the stocker is in the 60-70psi range.

Sounds like your lift pump isint adequate enough or you have a restriction in the supply to the cp3.
 
idk im running a new raptor 150 on it with a cat filter setup and all half inch lines. Turned pressure on raptor up to 30 and it would still drop
 
Might try to contact shane about it..he's a stickler about his products working right. I'm sure he will have a solution for you.
 
sounds good appreciate the help. might try switchin filters and makin sure there isn't an issue with one of them also
