I have already started a thread ab the topic of fuel injection to carb conversion. I have discovered the different ways proper and non proper and most cost effective methods of doing this right. Heres my thought, keep the stock pump in tank and lines and use a fuel pressure regulator. Now I know the stock pump puts out between 40-60 and the carb requires 6-10 psi. Now heres the golden question, **Does anyone know of a return style regulator that can block off and handle a 50 psi margin safely without blowing out and washing down cylinder walls? Other thought was if I were to run 2 regulators in series each one handleing a 20 psi drop??*** Thx Chris
