Steel fuel protector
The Anti-siphon, made of zinc-plated steel, works with heavy and medium duty trucks and features the original anti-siphon bent tubes to preventing theft or skimming. The product’s 5- to 6.5-in. length prevents skimming, and it has been tested to prevent splash back. The interior wall of the filler neck houses steel band grips to permanently place it, with no tools required for installation.
