It's winter, and I'm finally getting around to trying a webber 32/36 on the Chevy 153 in my CJ2a. Everything gf I've read says to limit fuel pressure to 3-5 psi for this carb. my mechanical fuel pump puts out 5-7. Is there a simple regulator that I could put in line which doesn't require a return line to the tank, and will work with the mechanical fuel pump?
