Fuel pressure problem..I'm at a loss.
what if you took that non bypass regulator and made it one: T off the input before the regulator, straight the carb and then regulate the pressure back to the return line? wide open (screw all the way in ) would reduce the pressure to the carb as it will be in full bypass back to the tank but on a smaller line so youll still have some pressure. Where are you measuring pressure? Jeez, run the darn thing with the cap off once and let us know. were gettign bogged down in "vapor lock" when 1 test can confirm this is or is not a tank venting issue. '69 Corvette fuel filters have a return spud on them, they have been used to cure vapor lock in the lines when they are forced to pass by a hot exhaust and start boiling the fuel in the line
