I installed a high flow fuel pump and my B&M can only lower the fuel pressure to 42 Psi. I decided to get the AEM FPR and it lowered my fuel pressure to 38 Psi. The AEM FPR came with 3 fittings anyone know wich one fitting will lower the fuel pressure lower? Here is what it says on the instructions. Black = .001 Gold .002 Silver .003

I want my fuel pressure around 34 but not shure what fitting I have to install inside the FPR.

 

the one with the biggest hole will lower it the most.

 

holy fawk the biggest hole? will lower it the most. how odd. thanx for the info now its time to rip my AEM apart and smell like gasoline again.

 

why do you want the fuel pressure to run so low? I have heard that 36-38 is the norm...
