Gas Cap Seal for use with most modern fuel caps found on many different make cars & trucks. Our seals measure approx 2" OD x 1.6" ID x 0.19" thick. Check your old seal to be sure it is approximately this same size.
Replacing this seal will usually cure the P0442 "check engine" error code that occurs when there is a leak in the fuel tank system. These codes are often related to a cracked or damaged fuel cap seal (see picture).
