I have a 59ab v8 flathead running a pair of holley 94's on an offy intake. I also have been suffering vapour lock issues lately so to cut a long story short I have fitted an electric pump as close to the tank as poss, junked the previous owners nasty attempts at inline filtering and fuel line routing which instanly leaked everywhere with the added pressure and then she ran sweet!...... for a trip round the block, then died at idle with fuel pouring out of the carb that previously didn't appear to be getting any. I put a gauge on the fuel line to check the electric pumps pressure and I appear to be getting 6psi which sounds too much to me. I have searched a number of threads a can't settle on a definitive answer. Can somebody tell me what pressure I should regulate my fuel to these carbs at please, it would be really nice to go out and drive for a change without it being just to check what my next problem is!
