the tiny o ring seal is very important as well make sure that is new and not deformed when installed in between the FPR. Also did you install the correct FPR for this app ?
Did you install a new GEN II cool fuel KIT ? There is 3 different cool fuel kitys to choose from just saying.

I am not even sure these pumps can produce 70 PSI? The max pressure they can produce is in absence of vacuum at the regulator, so start the motor and pull the vacuum line from regulator...most I get is 43-45 PSI on Gen II systems.

All I can say is 30 ish when idling and after a run the Gafrig was pined at 60 so I bought a hand held from a auto shop and that was reading 70 psi after a run .

Paul your referring to the device where the fuel line attaches to the rail? You are correct it is a pulse dampener and they manage fuel pulsing and limit noise, will have no affect on rail pressure.

many people think thats FPR on the fuel rails - I have been saying its the DAMPER for years up here - and I have posted this before (the Merc SB) as to what it is exactly.
