OER MA8173 1967-71 A-Body, Fuel Cap, Non Vented, Primer

Reproduction fuel cap for 1967-71 Dodge and Plymouth A-Body models. Manufactured as original, this non-vented cap comes primered and ready to paint and install. This cap is for models without ECS (Evaporative Control System) also known as EEC (Evaporative Emission Control).

To determine if your car had ECS originally look at the passenger side of the tank for various tubes sticking out of the tank and look for an expansion chamber inside the tank. If your vehicle's tank does not have these tubes and expansion chamber, then your car is without ECS (also referred to as EEC) and this cap should fit and function properly. If your car does have EEC/ECS, then your car will require part # MF10649 fuel cap.
