Key Features:

  • Capacity: 17-gallon fuel capacity matches factory specifications
  • Includes Filler Neck: Comes complete with the filler neck for a straightforward installation
  • Direct OEM Replacement: Drop-in fitment designed to replace original equipment tank
  • OEM Cross-Reference: Replaces GM OEM part number 22510103
  • Application: Fits Oldsmobile Cutlass Supreme Coupe, 1981–1988

This fuel tank is built to restore factory fuel system integrity in collision repair or routine replacement scenarios. The included filler neck ensures all components are ready for installation straight from the box, reducing the need for additional parts sourcing.

Bought wheels for a trailer, they arrived in a timely manner. The product picture was a little misleading but overall happy with the purchase.

Ordered replacement seats for my fishing boat. I was shocked and impressed with the quality of the seats. They look as good as the originals from Tracker. Shipping was great, arrived sooner than I expected.

I can't really grade the last one as the product has not arrived yet.

Everything arrived on time, exactly as advertised.

Great easy to use the website

Great service and product!
