A worn or loose-sealing fuel cap does more than let fumes escape—over a year, it can waste up to 30 gallons of gasoline through evaporation. The Motorad MGC829 is engineered by an OE supplier to meet OEM quality and safety standards, with pressure and vacuum relief valves specifically designed to keep fuel vapor where it belongs. Built to pass all state and federal emissions testing requirements, this twist-lock, round-style regular fuel cap is a straightforward replacement for aging or damaged original caps on select 1972-1984 Subaru, Dodge, Plymouth, and Mitsubishi models. Constructed from metal, plastic, and rubber components in a silver finish, it's a simple, reliable way to restore proper fuel system sealing and stop unnecessary fuel loss. Confirm fitment against your vehicle's year, make, model, and engine before ordering.
