FUEL CAP
The Leak Defender ® is a 2-piece fuel neck repair/replacement system consisting of a new and improved fuel neck + fuel cap. We designed it to stop fuel cap leaks for good. 100% money back guaranteed! Even if your fuel neck threads are completely worn/stripped and fuel caps no longer seal, it will work! In fact, this is why we invented it.
It is machined from wear-resistant 6160 aircraft billet aluminum allowing it to be made with a high degree of precision and with the strength to withstand everyday wear and tear. It should easily last the lifetime of your truck. It also features premium 1/4″ thick Buna-N/Nitrile o-rings and deep fuel cap + neck threads.
NEW & IMPROVED FUEL NECK –
REPLACES OEM FUEL NECK
The star of the show, what stops leaks for good, is the Leak Defender® fuel neck replacement. It has a thick 1/4″ Buna-N/Nitrile o-ring underneath which seals to your OEM fuel neck when tightened with a strap wrench. It is sealed along the outer perimeter, away from the inner perimeter which is prone to wear and tear from everyday fueling. It is securely fastened with set screws. No welding or downtime required.
We have improved upon the OEM design of a big rig’s fuel neck by machining the Leak Defender® from wear-resistant 6160 aircraft billet aluminum and engineering deeper threads.
