Product Details

The MGC203KA fuel tank cap is built for vehicles that use a threaded filler neck and require a locking, vented cap. Its emission-control design helps maintain proper tank pressure while limiting evaporative fuel loss. A worn or leaking cap can create drivability and emissions issues, and it can also allow fuel vapor to escape over time. This part cross-references Carlson 17501 for the same application.

Fits 2002-2003 Ford F-150, with threaded filler neck. Fits 1997-2001 Jeep Wrangler, Key Vent Keyed Alike. Fits 1996-1998 Chevrolet Express 2500, Key Vent Keyed Alike. Fits 1994-2000 Nissan Pathfinder, Key Vent Keyed Alike. Fits 1993-1997 GMC Yukon, Key Vent Keyed Alike.

What It Helps Solve

• Fuel vapor leakage from a damaged or loose cap
• Check-engine concerns related to evaporative emissions sealing
• Loss of tank pressure or vacuum retention
• Security concerns on vehicles that use a locking fuel cap
• Replacement needs for worn threaded filler neck caps

Installation Notes and Tips

Confirm neck diameter, shell diameter, and filler-neck style before ordering. This cap is intended for threaded filler neck applications and should be tightened until fully seated and locked. Verify that the vehicle uses a vented, locking cap style and compare the existing cap profile to the listed dimensions for proper fitment.

Quality Assurance

Motorad manufactures this cap to OEM-quality standards and to meet state and federal emissions requirements. The pressure and vacuum relief valve design supports fuel-system sealing and evaporative emissions control.
