Not sure what it is that's happening but as I drive (then stop)the 66 B20 powered Estate I can see and hear bubbles going through the fuel filter.
I also notice fuel stains on the 1/4 panel from fuel seeping past cap.
I loosened cap and heard a woosh. No more bubbles. At first I thought it was from heating up the fuel line as its pretty close to the block and t-stat housing. Now I have to wonder if I should use the vented fuel inlet I took off
the 68 Estate parts car.
It has a 32/36 Weber carb if that matters.
It does start hard after sitting. Ideas? Thanks in advance!
