Description
Gas Tank – 31 Gallon – Gas – 1987–1991 Chevy GMC Blazer Jimmy Suburban 2WD 4WD
The Gas Tank – 31 Gallon – Gas – 1987–1991 Chevy GMC Blazer Jimmy Suburban is an OE-style replacement fuel tank engineered specifically for 1987–1991 gasoline engine Squarebody SUV models. Designed to restore factory fitment and increase fuel capacity, this tank is correct for 2WD and 4WD Blazer, Jimmy, and Suburban applications equipped with gas engines.
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 ribs, mounting flanges, holes, and curvature to mirror original GM production specifications. Accurate stamping ensures proper alignment with factory mounting points and surrounding chassis components.
Unlike earlier non-baffled designs, this 1987–1991 gas application tank includes the correct internal baffle for fuel-injected trucks, making it appropriate for late Squarebody throttle body injection (TBI) systems. Proper baffling helps maintain consistent fuel supply under acceleration and varied driving conditions.
All AMD fuel tanks are pressure tested for leaks prior to release, supporting reliable fuel containment and long-term durability. This tank replaces GM part number 15578064, restoring the correct 31-gallon configuration used in late-model Squarebody Blazer, Jimmy, and Suburban gas applications.
With its larger 31-gallon capacity, this tank provides extended driving range while maintaining factory-style underbody appearance. It is ideal for stock restorations, fuel system repairs, or capacity upgrades on 1987–1991 gas-powered Squarebody SUVs.
