Restore your 1981-1986 Mustang's fuel system to factory-correct form with a direct-fit replacement tank that matches original dimensions, capacity, and mounting points exactly. Built for cars equipped with an external fuel pump and no fuel injection, this 15.4-gallon rear-mounted tank drops in without cutting, fabricating, or sourcing adapters.
Direct-fit replacement, no guesswork. The tank replicates the OEM rear-mounted configuration for 1981-1986 Mustangs produced from April 1, 1981 onward. It accepts the factory filler neck, OE-style fuel sending unit, and original mounting straps, so the installation uses the same hardware already on the car.
Pressure-tested and corrosion-resistant. Every tank is pressure tested before leaving the factory to confirm leak-free integrity. A protective coating applied to the exterior shields the steel from road moisture, salt, and underbody grime, extending service life well beyond what a degraded original tank can offer.
OEM compatibility throughout. The tank is engineered to the same interface dimensions as OEM part E4ZZ-9002-B, so the fuel sending unit, filler neck, and mounting straps all locate and seal correctly without modification.
