Okay this is what i have
Stealth ram fuel rails
kirban adjustable regulator
new fuel filter
new walbro 255lph with wiring

I cannot get the fuel pressure to increase past 40 PSI and ive dialed the regulator almost all the way, and the pressure doesnt change whether the vacume line to the reg is on or off.. whitch is very strange also. pressure for startup[ is 37 psi running idle at 900 rpm is 40 psi and when you give it throttle it goes down to 30PSI.
Why can i not increase pressure?

 

HELP!! someone must have an idea voltage to pump when running is 14 somethin volts as seen while i datalog on the autoprom

 

May have been a problem with the fuel pump installation.
It's common to have leaks in the tank if it isn't installed just right.

 

hmmm.... i suppose the only way of telling would be to takew the tank out... errg. But im pretty confident i installed it correctly.. brand new sock, deleted the isolator etc. ANy other opinions?
