FTA-3-7 Volvo, Mack & International 3" Anti-Siphon Device

It helps stop siphoning by blocking access through the fuel fill neck, making it difficult to insert a hose for unauthorized fuel removal. This supports fuel theft prevention while allowing normal refueling. It’s a simple upgrade for anti-siphon fuel tank protection and added truck fuel cap security.

It’s designed specifically for Volvo, Mack, and International fitments where a 3 inch anti-siphon device is required. Confirm the fuel fill neck size before ordering to ensure the correct match. Proper sizing is key to effective anti-siphon fuel tank protection.

It adds an internal barrier behind the fuel cap, so even if the cap is bypassed, siphoning is still prevented. Pairing it with a locking cap can improve overall fuel theft prevention for parked or unattended trucks. This layered approach is especially helpful in high-risk areas for fuel theft.
