Leak Defender® for Volvos

SCREW-ON FUEL NECK + 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. 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 6061 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″ Buna-N/Nitrile o-rings and deep fuel cap and neck threads.

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 Volvo 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.

It also features a 10″ safety chain and 6″ bail to help prevent loss during refueling.

NOTE: Sold individually, not as a pair. Fits Volvo models w/ 3″ fuel filler neck.
