Good point on the fuel filter. When I bought the truck, it had a glass bowl fuel filter mounted just before the carburetor. I had trouble with the fuel boiling in the filter, so I removed it, put in a new fuel line and wrapped it with insulation. But never replaced the fuel filter now that you mention it. I have historically used a standard NAPA fuel filter on my 62 Plymouth and never had an issue, is that the type of filter you are referring to. About an inch and a half in diameter. But I’m still left with a question why this only seem to happen in very hot weather?
