the fuel filter/regulator will supply 59 psi of fuel and under full throttle you will get 57 to 58 pst.
on all my crossfires i have replaced the filter/regulator with a manual regulator, and i do not use the vacuum line which increases
psi as the rpm goes up. also if u do install a manual regulator,u must have a return line from the regulator to the tank.
i do this so i can set my psi to the afr's so i get max H p .
