Gates 31615 Pre-Release Fuel Cap

The Gates 31615 Pre-Release Fuel Cap is built for specific late-model and earlier threaded-filler-neck applications that require an emission-control style fuel tank cap.

Installation Notes and Tips

Verify the filler neck style before ordering. This cap is for threaded filler neck applications and is not a lockable design. Match the vehicle year, make, and model exactly, since the fitment list includes many application-specific notes such as pre-release, threaded filler neck, and model-year cutoffs. For best results, inspect the filler neck threads and sealing surface before installation.
