Detailed Description

The Motorad MGC204KA is a locking fuel tank cap engineered for emission-controlled fuel systems. Its relief-valve design helps regulate pressure and vacuum in the tank, reducing evaporative loss and supporting proper sealing at the filler neck. This matters on vehicles such as the Ford Explorer, Ford F-150, Ford Taurus, Lincoln Navigator, and Mercury Mountaineer where a worn or leaking cap can trigger drivability and emissions concerns.

This part cross-references Carlson 17502 for the same application. The MGC204KA is also referenced under Motorad MGC204KA and interchange number 703-1592.

What It Helps Solve

• Fuel vapor leakage from a damaged or worn cap
• Check engine light concerns related to evaporative emissions sealing
• Loose, cracked, or missing locking fuel cap issues
• Fuel odor caused by poor tank-cap sealing
• Evaporative fuel loss from a cap that no longer holds pressure correctly

Installation Notes and Tips

Verify filler neck diameter, locking style, and vehicle application before installation. This cap is listed with a 1.750 in neck diameter and is intended for specific keyed-alike applications, including select Ford, Lincoln, Mercury, Jaguar, and Mazda models. Confirm the cap style against the original equipment cap on the vehicle before purchase.
