I've got a '93 Quest... light smell of gas in the car all the time.
I definitely had some issues with the lines at the tank and the vent hose. I had the dealer do the recall on the vent hose. I had to do the fuel pump too so I replaced all the hoses on the tank at that point. That stopped 95% of the problem but there is still a light scent of gas coming from somewhere. No obvious leaks, fuel filter hoses are good and tight, I can't actually feel any moisture on anything.
Where next ?
