On many cars, a fuel smell is from a crack in the coupling hose from the outside filler to the tank on '73-up models. And for reasons that escape me, the crack is nearly always on the hose's bottom where its harder to see. Some of that hose cracking comes from people using radiator hose instead of fuel proof hose in that position while others are from simple age Might be worth a close look.
