The Leak Defender® is more than just a shiny new fuel cap….it is a 2-piece fuel neck adapter consisting of a collar and cap which creates a completely NEW sealing surface, replacing your old fuel neck. The collar has an O-ring underneath which seals to your existing fuel neck when tightened and is securely fastened with set screws. It is sealed along the outer perimeter, away from the inner perimeter which is prone to wear and tear from everyday fueling.
The fuel cap twists onto the collar, your new and improved sealing surface which is built to last…made with the strength of billet aluminum. In under 5 minutes, you can say good-bye to constantly replacing your fuel cap, creating makeshift remedies or replacing your entire fuel tank just to stop fuel cap leaks.
NOTE: If you have dual tanks, you will need to purchase 2.
