2-PIECE FUEL NECK
The Leak Defender® is a 2-piece fuel neck replacement system consisting of a collar and cap. It stops leaking fuel cap issues on Kenworth, Peterbilt and Freightliner trucks…100% money back guaranteed!
REPLACES YOUR OLD, WORN
The collar creates a completely NEW sealing surface and replaces your old, worn fuel neck. The collar has an o-ring underneath which seals to your existing fuel neck when tightened with a strap wrench 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.
NEW & IMPROVED FUEL CAP
Also included is a new and improved fuel cap. It’s machined from billet aluminum allowing it to be made with a high degree of precision & with the strength to withstand everyday wear & tear.
