Parts Desk Insights

Best Use Case: Ideal when you want to secure a Perko-style 1-1/2″ vented fuel deck fill by upgrading to a keyed locking insert rather than replacing the entire fill assembly.

Common Issues: If the lock cylinder doesnt align smoothly during installation, re-check orientation and mating surfaces on the deck fill opening; also confirm youre working with the correct 1-1/2″ vented fill style before installing.
