Jag..,
No doubt I am not a Holley lover since the early 60's
blown power valves with as little as one backfire, float settings being a night mare, etc. however ONCE right they really can't be beat.
I also completely understand what you are saying, it's kind of like a biblical passage to electric fuel pumps. That is why, the way I have this set up the pressure of the fuel in the tank will force the fuel to the height of the pump on it's own,
Tommy you just filled in the missing blanks for me. Why does it only have 4.5 PSI and no regulator. (Still haven't found the regulator) It also explains why cracking the line at the filter lets the air out and the pressure immediately jumps to the 4.5!
Got time today so will follow the line from tank to filter to carb/fuel log to see if Ed's mechanic didn't install a pressure gauge somewhere. I never installed a pressure regulator as using the Carter fuel pump and a Edelbrock Carb. a regulator would be redundant!
