Gas Tank – 40 Gallon – 1974–1981 Chevy GMC C/K Suburban 2WD 4WD
The Gas Tank – 40 Gallon is an OE-style replacement fuel tank designed for 1974–1981 Chevrolet and GMC C/K Suburban models, including both 2WD and 4WD Squarebody applications. This large-capacity tank restores factory fitment while delivering extended driving range for full-size Squarebody Suburban builds.
Manufactured as an AMD OE replacement, this fuel tank is stamped from high-quality rust-resistant steel and finished with a protective zinc coating to help resist corrosion. Each tank is formed with the correct factory-style shape, ribs, mounting holes, flanges, and curvature to mirror original GM production specifications. Proper stamping ensures accurate alignment with factory mounting locations and surrounding chassis components.
All AMD fuel tanks are pressure tested for leaks prior to release, supporting reliable fuel containment and long-term durability. This tank features a non-baffled design, consistent with original production for applicable Suburban configurations of this era.
With its substantial 40-gallon capacity, this tank is ideal for extended highway driving, towing, or long-distance travel where additional fuel range is beneficial. It replaces GM part number 475429, restoring the correct high-capacity configuration used in 1974–1981 Squarebody Suburban models.
Designed specifically for classic Chevy and GMC Suburban restoration projects, this fuel tank delivers factory-style construction, proper fitment, and increased range capability while maintaining correct underbody appearance.
