I would agree with completely cured paint, but it could be somewhat green yet. They say concrete in bridges can take 30 year of more to finally completely cure. There was some painted panel on my '68 vette that I wanted to strip and repaint and 3 attempts using aircraft remover wouldn't touch it! I ended up just cleaning the original paint and leaving it. That stuff was the toughest paint I have ever seen. Probably had lead in it.I wouldn't think that paint would cause any issues. Ideally it should probably be bare metal though.
Did this take care of your fuel leak issue?Yeah I have been thinking of cutting off the hard plastic lines and going with flexible pressure rated hose as others have. Not a huge fan of bending the hard plastic lines for install and the rubber lines look better in the car i think. I am going to pull the pump tomorrow while it rains and I will check for cracks and take care of the paint issue/grease the o-ring and reset it. I might change the hose to rubber ones too while I am at it. Still waiting for title and registration anyway.
