When using the flush-mounted gas caps, you may encounter the uncommon issue where the spring becomes stuck on the internal shaft of the gas cap mechanism. This situation arises due to the fuel vapors causing the factory-applied lubricant to dry out, which can lead to insufficient lubrication for the moving spring involved in the gas cap's operation. As a result, the gas cap may not function as intended, potentially leading to difficulties in opening or closing the gas cap properly. It is advisable to apply lubricant to the internal components to help free the spring.
