The plumbing around the gas tank is mostly plastic and susceptible to aging, but there doesn't seem to be any single thing that always fails. And it often seems to be worse when the tank is close to full, instead of close to empty, maybe? What you can do is, get it into a shop with a good hydrocarbons sniffer, the probe they stick in the exhaust pipe for emissions tuning. You'll have to remove some interior trim to get access to a lot of stuff in the rear, above and around the (plastic) gas tank, and then along the fuel lines running up to the engine. With luck, you'll put the probe near a fitting that causes the HC meter to jump. And there may be more than one, so keep looking. All that stuff ages at about the same rate. That said, I've got one now that I never have been able to track down. So I live with it, and when I go to sell it I'll make sure the tank is 1/4 full... -- Good luck, Buddy Buddy Donnelly
