Another Fuel tank thread - 71 Demon

Show me a picture of the back side of the gas cap and the inside end of the fill tube.. I have 2 late build Demons and also had several Duster and Demons in the past. All my 71;s had the . Vent tube. If you bought the car in 84 that means it was 13 years old before you owned it. Many collision shops would use 70 Dusters and 72 demons to clip 71 Demons in the early 70's for insurance co. repairs at dealers. Even 73's were used. Done right you would never tell.

I am not saying you have one but its worth a look. Send some pictures of your gas cap that would be the first clue. If the tank had one single vent in the front it is a 72 and newer tank. That hose went to the charcoal canister. I ran that tank in a 71 and ran the vent tube to the three nipple 71 oil breather.

Does your car have the correct oil breather and what is it connected to. Pictures would help. Does it have a rally dash. how about the screw hole that held the passenger side exhaust hanger on. Many think they know what they have because they have it for many years.

What I would do? Not saying I have any experience at this is use an extra tank pad and add a folded piece between the tank and the front of the tire well. Make it three thick . Not saying I ever did this but it should work LOL
