Dorman Fuel Tank Strap for GM Full-Size Sedans

Dorman 578-022 is a direct replacement fuel tank strap for select Buick, Oldsmobile, Pontiac, and Cadillac vehicles. Built from steel with a silver finish, it is made for fuel tank service on applications such as the Buick LeSabre, Oldsmobile 88, and Pontiac Bonneville.

Key Features

  • Steel construction for strength and long-term support
  • Silver finish
  • Direct replacement for the original fuel tank strap

Detailed Description

This Dorman fuel tank strap is engineered as a direct replacement for the factory strap used on a range of GM rear-wheel-drive and front-wheel-drive sedans. The steel construction is intended to hold the fuel tank securely in place while resisting harsh road and weather exposure. With strap lengths of 32 inches and 31 inches and an 8-inch width, 578-022 matches the original-style layout needed for proper tank support on vehicles including the Buick LeSabre, Oldsmobile 98, and Cadillac DeVille. This part cross-references Motorad ST22 and OE reference 22518121 for the same application.

What This Part Helps Address

  • Corroded or weakened fuel tank straps
  • Fuel tank movement caused by damaged mounting straps
  • Service needs during fuel tank replacement
  • Support issues from road salt, moisture, and weather exposure
  • Restoration work on older Buick, Oldsmobile, Pontiac, and Cadillac sedans

Installation Notes and Tips

Inspect the tank, mounting points, and surrounding hardware before installation. Replace the strap when the fuel tank is removed for service, and verify that the strap shape and length match the original application before tightening. Because installation hardware is not included, reuse or source the correct fasteners separately as needed. Confirm vehicle-specific fitment for your exact year and model before ordering 578-022.

Quality Assurance

Dorman manufactures this strap as a direct replacement part using durable materials for demanding road conditions. It is built to follow the original fit and function expected for fuel tank service on compatible GM applications.
