    Bought this seal chasing down a P0455 gross EVAP System leak. The seal looks and fits exactly the same as the factory installed seal on my 2004 GMC Sierra 5.3L V8 pickup. Turned out the real problem was the Vapor Canister Vent Solenoid.

    Exact replacement for my 07-13 Silverado cap. Old seal was smashed and and not sealing, resulting in check engine light code. Swapped out this seal and took care of problem.

    Grate vs new gas cap. NM dry heat eats up rubber.
