Product Details

Motorad’s Heavy Duty Fuel Tank Cap line focuses on dependable fuel system sealing and emissions control. The 2003-11 fuel cap is designed to support proper tank pressure management while limiting evaporative fuel loss, which is important for vehicles that rely on a vented cap design. As a replacement fuel tank cap, it is suited for routine maintenance when the original cap is worn, damaged, or no longer sealing correctly.

This part cross-references CSF 10603 for the same application.

What This Fuel Cap Helps Address

Installation Notes

Inspect the filler neck and sealing surface before installation. Confirm that the replacement cap matches the vehicle’s vented, non-locking fuel cap requirement and tighten it until it seats securely. After installation, verify that the cap closes fully and that any evaporative emissions concern is cleared according to the vehicle service procedure.
