What exactly are you worried about with the fuel pressure?

hate to write this here and now but somebody has beeten us to this, in the 80's ford had an in tank fuel pump and carb. they used a pressure regulator that had a built in return line, what was not used to keep the carb at a certain pressure went back to the tank, it has been done several times before on tbi engines and i bet if you did some digging, you can find older threads about it

i putt a fuel pressure regulator on it and it runs pretty good but now im having problems tuneing the carb... its a edelbrock 600 with the 2 screws in front.

what are the problems, too rich, lean, doggy, runs too good?

chadb2008918

honestly its really sluggish. at first i had the timing 180 out and now. its fine but it acts like its running a lil bit to rich...

is the fuel pressure regulator adjustable?
