Got a HOLLEY problim

I've used RTV in lots of "fuel situations." You do need to give it adequate drying time, 48 hrs if possible.

"In a previous life" I punched a hole in the side of the tank on my 70 440-6 car. Big Rock. We nursed it to the shop, jacked it up to get the fuel "to the other side" and slathered it with RTV, left it overnight. That was about 1972 and it was on the car when I sold it about 1977 or so.
