Sierra 18-6501 Fuel Tank Gasket, Replaces OEM 302557, Package of 2

The Sierra 18-6501 Fuel Tank Gasket is a direct-fit replacement gasket engineered to replace OEM number 302557. It is sold as a package of 2, so you get a matched pair of gaskets in a single purchase rather than having to order two separate units. The gasket is designed to seat between the fuel tank and its mating surface to maintain a tight seal, helping prevent fuel leaks and vapor loss at the tank connection. Because it is manufactured to the OEM 302557 reference, it is intended to install as a drop-in match without modification for applications that originally used that part number.

Each package weighs 0.3 pounds, making it a lightweight, low-cost maintenance item that is easy to keep on hand as a spare when servicing a fuel tank. As a Sierra branded part, it carries the manufacturer part number 18-6501 for easy reordering.
