I've been having problems with an occasional fresh gasoline smell. I ruled out any leaks in the engine from any fuel hoses. The gas cap is firmly on and no gas smell from there. The strongest gas smell comes from the fuel pump itself. The hoses to the fuel pump and metal fuel line are tight and dry. The top of the fuel pump is dry. The only thing I can find is there appears to be some gas between the fuel pump and the rubber boot where the fuel pump goes into the tank. The rubber boot seems to be in fine shape, not hard or anything. Anyone hav this issue and how to fix this?
