thanks to all who replied, I use a BG 280 with #12 line from the fuel cell to the pump #10 line to the regulator and #8 line from the regulator to the carb. My question was, does fuel pressure say set at 6 , 6 1/2 or 7 psi have any effect. And how much fuel pressure can the needle and seat withstand.
