CAP COMP.,FUEL FI

Sooner or later the locking mechanism seizes up, either stopping the fuel tap from coming off, or from going back on securely. If the various sprays and anti seize compounds have failed, and they usually do, then buy a brand new filler cap and stop worrying about getting it off and on!

• Buy it - Fit it and forget it! Not quite, protective wax regularly applied will keep the item in good shape indefinitely!
