Hi all!
I built ERA 427 SC # 491 about 24 years ago. It has about 5000 miles on it. Pete had the 427 SO built locally there.
My single Holley 4160 has been running overly rich with gas dripping from venturis and flooding the plates and pooling into and out onto the medium rise intake. I have adjusted the floats and replaced the perishable components in the carb. The 6.5 Powervalve holds vacuum OK.
I did a pressure test of the fuel pump and came up with over 10 psi. My gauge goes up to 10. The fuel pump is a mechanical Carter 0-3000 that does not have an overflow nipple on the upper half.
I think this car has always run rich but otherwise runs well most of the time.
My solution is to put a pressure regulator on the fuel line between the pump and carb. What regulator would you use?
I would consider lowering the floats a little but am running out of threads on the fuel inlet using a thicker nylon washer on the 5/8 " hex nut.
I have not bent the tang on the float hanger.
Any thoughts?
