Ok, so last week, I took the fuel pump, etc off so I could put an oil pressure guage on my 68. In the process, i must have bent the fuel line just enough to open up a pinhole leak in the line running to the fuel pump (I have a 2 piece fuel line) and i had a pretty good gas leak. So today, I got a 12" long section of 5/16 hose and replaced the corroded part. It was corroded where it passes through the part of the body under the floor pan. Not sure what that is called. Anyway, when i started it up today, gas was coming up out of the vent on the secondary bowl. Surely that small section of rubber hose would not cause all of that. Any ideas? I have a clear gas filter on it just before where it goes into the carb and a factory rebuilt holley. It ran FINE before taking it apart.
