Locking Fuel Cap with Anti-Siphon Protection for Cars, Utes & Vans

THEY WAIT UNTIL YOU'RE ASLEEP. THEN THEY GO FOR YOUR FUEL.

Fuel theft has become an expensive reality. A full tank can represent well over $100 worth of fuel — and siphoning often leaves little to no evidence behind.

The Fuel Defender is designed to help protect your fuel tank with a heavy-duty locking system and an integrated anti-siphon barrier that helps prevent unauthorized access.

A LOCKED TANK IS A HARDER TARGET.

Most factory fuel caps can be removed in seconds.

The Fuel Defender replaces your standard cap with a reinforced locking cap that can only be opened using the supplied key.

When thieves are looking for easy opportunities, visible security can make all the difference.

Heavy-duty construction designed to help resist tampering and unauthorized access.
