I have a 93 SC with 42# injectors, 76mm maf, ported heads and intake, 255lph fuel pump. I just put an adjustable fuel regulator on it and I am gonna go buy a fuel pressure guage tomorrow. What kind of fuel pressure should I be runnning?

quoted from david neibert the "sofa king"

"Set the static pressure to 40 psi with the engine idling and the vacuum/boost refrence line off. If the engine boggs under hard acceleration from a stop increase the pressure 1 or 2 pounds. That will usually be enough to correct any problems. Don't go over 43.5 static pressure.

I've had several adjustable regulators over the past 3 or 4 years and they all failed (stuck, leaks ect...) so now I'm using the stock regulator and a dyno tuned chip for A/F ratio adjustments.

Re:Adjustable fuel press regulator

If I want to use a Kirban regulator, what model should I ask for?
 
Hey George, you will need the two hole model for your 94 SC rail. So pick the 94-98 Mustang application. KPP5018
