I'm turbocharging my 1982 Yamaha motorcycle. Since the carbs were gravity feed I now need a fuel pump and rising rate regulator. Fuel pressure needs to go from about 2-10 psi. I stopped working on the bike a few months back because I can't find a rising rate regulator that isn't crazy expensive. I don't need much flow.
Does anyone have any idea where to buy decent reasonably priced parts that might fill my need?
