The Leak Defender® is more then just a shiny new cap….it is a 2-piece system consisting of a collar and cap which creates a completely new sealing surface. The Leak Defender® Collar attaches to your existing fuel neck, sealing along the outer perimeter, away from the inner perimeter which is prone to nicks and abrasions. The Leak Defender® cap attaches to the collar and is made with the same billet aluminum to withstand the wear and tear of everyday fueling.

NOTE: If you have dual tanks, you will need to purchase 2.
