Detailed Description

Dorman 576-406 is a replacement fuel tank designed for vehicles that use a filler neck and require an OE-style tank shape and mounting profile. The steel body measures 39.625 inches long, 21.25 inches wide, and 10.25 inches high, with a silver painted coating for added surface protection. This tank is built for 1975-1979 Buick Skylark, 1975-1979 Chevrolet Nova, 1975-1979 Oldsmobile Omega, and 1977-1979 Pontiac Phoenix applications. This part cross-references Spectra Premium GM202 and VNE 344416 for the same application.

Common Issues This Part Can Address

• Fuel tank corrosion or rust-through
• Leaks caused by a damaged or deteriorated original tank
• Fuel odor from a compromised tank shell
• Restoration needs for classic Buick Skylark, Chevrolet Nova, Oldsmobile Omega, or Pontiac Phoenix fuel systems
• Replacement of a tank that no longer seals properly with the filler neck setup

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and filler neck configuration before installation. Mounting straps are not included, and the sending unit, filler neck, and fuel tank straps must be sourced separately if needed for the repair. Inspect the lock ring and O-ring sealing surfaces during installation to help ensure a proper seal.
