Default Fuel filter

I have a 1977 corvette. My question is when I start it up the fuel filter is full of gas and if I let it idle for five min it stays full. If I drive it for 10 miles and then check it the fuel filter is half full. Is this correct or do I have a problem? Thanks

Seems like the problem might be having a see through filter. Is it glass? With rubber hoses?

Plastic is better than glass for a filter, we hate seeing corvettes burn up. The gas level in the filter doesn't sound like a problem, probably changes with the under hood temperatures. What carb are you using?

Those carbs are hard to build a steel line to and have a filter inline. If you're interested you can e-mail Lars for his how to papers on making fuel lines,. he may have an opinion on the gas level in your filter.

It's normal for the filter to only be partially filled with fuel when running.
