84 V20 fuel tank question?

The gasket at the sending unit may be cause of faint smell.
Look at the screw holes for the sending unit and the grounding tab. look at the elbow and the hose barb...If the aluminum is corroded there, its probably corroded in hidden places too.

Not familiar with the layout of the center console tank. Is it foamed in?
Problem is, you can't see corroded tank when covered in foam.
30 years is a long time for an aluminum tank in a salt environ...
