SCREW-ON FUEL NECK + FUEL CAP + ANTI-SIPHON
The Leak Defender® + Anti-Siphon is a 3-piece fuel neck repair/replacement system consisting of a new and improved fuel neck + fuel cap + anti-siphon. We designed it to stop fuel cap leaks for good. 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. We also included an anti-siphon to help heavy-duty truckers and fleet owners from having their diesel siphoned off by fuel thieves.
The Leak Defender® anti-siphon is quick and easy to install…just drop it into your fuel neck and screw the Leak Defender® fuel neck on over it which is then secured in place with set screws. It’s superior to the basic anti-siphon on the market as it features a thick, tamper-resistant 6061 aircraft aluminum barrier and features vents just big enough to allow rapid fueling yet small enough to keep fuel thieves from siphoning off your diesel.
NEW & IMPROVED FUEL NECK – REPLACES YOUR 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 design of the OEM Western Star fuel neck by machining the Leak Defender® from wear-resistant 6061 aircraft billet aluminum and engineering deeper threads.
NEW & IMPROVED FUEL CAP
The Leak Defender® also includes a new and improved fuel cap that not only looks impressive but outperforms any fuel cap on the market. With attributes like wear-resistant 6061 aircraft billet aluminum, a thick 1/4″ Buna-N/Nitrile o-ring and deep threads, it’s sure to impress. In fact, we 100% money-back guarantee it.
NOTE: Sold individually, not as a pair.
