Lots of times when folks search online for a similar problem the end resolution is missing..... this is how this one got resolved. I did a fuel pump pressure test on the new Delphi "exact replacement" for the factory 6 cylinder fuel pump. Well dimensions are the same but the new pump is much more powerful (over 12 + lbs) compared to the old pump. The ethanol was getting frothy and the brass float in the little Rochester Monojet could not fight the pressure. I was told by the gentleman at the FLAPS that the new Delphi (China made I learned) pumps are all higher pressure than stock and with original equipment may create too much pressure. I cleaned up the old pump and did nothing else but swap them and the old 6 cylinder purred...20 mile run out and back. So much for thinking a new fuel pump would go good with the new brass float and bits. Aw Dang and Joe H thanks.
