I'm replacing the mechanical fuel pump for my 72 142s (b20b w/dual SU's). Bought the IPD pump and spacer. The previous owner had a fuel pressure regulator in the fuel line after the pump. I've read some posts that say the mechanical fuel pump puts out between 4 to 6 psi and that the SU carbs only like 1.5 to 3 psi.
Would you recommend me keeping the fuel pressure regulator in the fuel line? Any good way to determine if the old regulator is actually keeping the right psi?
