stock pump return line help

[abodyhotrod]

prob on maiden voyage i started cruisin and 10 min later my brand new holley carb starts blowing gas past the seats out the top of the carb. i am running with no return line, can that cause it when it gets hot. the fuel filter is that p.o.s. glass one that i will not use much longer but the gas seems clean so no dirt stuck on the seats. anybody know if the stock fuel pump requires a return line i heard that they do have a blow by in the pump itself but causes it to heat up the gas and vaporize it.

i planned on waiting for it to cool off but that didnt work it still blew right out the top. can anybody recomend a good 3 way filter for the return line.

sounds like crap in the seats, maybe even from manufacturing.... i have seen some real big pieces even , once a spiral chip from a drill bit. you never know...

Yep, take the bowls off, check float level and check the needle and seats.

A stock pump shouldnt have that much pressure. I would pull the carb apart and clean it out. If you still have the problem put a pressure gauge on it before the carb.

Replace that glass filter with a metal one asap. The glass can brake.

exactly, it was a dirty seat.

seems to me the quality @ holley went south. i`ve been using their stuff since the late 60`s, (yup, that`s a long time ago!) sorry to say, i`m hearing a lot of negative toward their products.
