1963 Chris Craft Caviler electric fuel pump showed air bubbles. Pressured fuel line, no leaks. Where is this air coming from?
And how to access the fuel tank to check pick up? Do I have a cavitation problem?

Need to know how to check for this type of problem and what to look for to correct the fuel pump from sucking air.

Thank you in advance, Leon

I would hook up a portable tank where the old tank hooks to your fuel line. If that fixes it your tanks hardware or the fuel pick up tube is bad.
