This Loc-Sure is a non-vented, screw-in, locking billet cap for the diesel filler neck on the 2008-2017 Ford diesel trucks (F-250, F-350, F-450, F-550) with 6.7 L POWERSTROKE engine. This is designed for the 2017 model year. This is compatible with 2012-2014 filler necks, and 2017-2019 filler necks. SOME 2015, 2016 and 2020 filler necks are compatible. Check carefully.
The Loc-Sure offers protection from fuel thieves and from malicious people who would contaminate your fuel. The Loc-Sure utilizes the parent company's Secure Screw system which has been tested and approved by military and other secure facilities as a low-level human secure system.
The Loc-Sure features a 2.5" diameter top face with scallops and knurling for good gripping. The U-Cup seal contacts both the inside and the outside diameter of the fuel filler rim to ensure a proper seal.
Each Loc-Sure purchase comes with the Loc-Sure cap and a fully machined stainless steel Secure Key pair with complimentary stainless steel key ring. Additional keys can be purchased using the information from our Keys page.
BEM Auto's Loc-Sure body is fully machined from aluminum bars at the BEM Auto factory and is finished in a generic green anodized surface, etched to identify the assembled unit as a diesel only cap. The Secure Screw is manufactured from 18-8 stainless steel to provide good corrosion resistance.
