Yep. Fresh Fuel Filter
Ive got it plumbed with the fuel line from the rails going into the top port and coming out the bottom going to the fuel tank return.
Tomorrow Im going to run an OEM
FPR in the SARD's location. If my problem goes away, it will confirm the dead SARD
FPR.
I have also checked for leaks. I clamped the return line to push the pressure up over 60psi and checked all the new fittings and no problems.
