Fuel Filler Neck Alternative for 70 Duster
The Classic Industries 67-69 Dart/ Valiant fuel neck should work with your 70 Duster if the dimensions of the neck are the same. If the neck dimensions are the same then you would probably have to use the vent tube from your Duster because it looks different. 70 non EEC A-Bodies use the same non vent fuel cap as the 67-69 cars. This is the one out of my 70 dart. I replaced it with a restored one and reused the vent tube out of my car.
