2-3psi MAX.
Tim..
Get a regulator, and a decent pump that does about 10 psi... Set it to 2 to 3 psi.
Then you will ALWAYS have 2 to 3 psi regardless of flow...
And fit a small jet or orifice that feeds a return pipe back to the tank, of say 1 to 2 mm so that fuel always flows. Because then pressure cariations are minimised, and fuel is never "stood" long enough to boil due to heat and cause vapour locks. And everything is under less stress.
ok, thaks for the help.
