Locking Caps

Diesel fuel theft is a challenge all fleet managers and independent owner/operators must face on an increasing basis. The cost of a lost tank of fuel adds up, and the downtime waiting for refueling cuts into the delivery schedule. Bud and Tony's Truck Parts is the online authority for locking fuel caps, enhancing vehicle security with a large selection of locking fuel caps, locking fuel covers and secure DEF caps.


Semi-truck anti-siphons create another layer of defense against diesel fuel theft, preventing thieves from reaching fuel reservoirs. We carry patented anti-siphons built from quality materials and made for simple self-installation into all the major truck brands, and they're guaranteed for the lifetime of the fuel tank. Add locking fuel caps and covers for more security, and rest easy knowing the supply is protected.

Tank Straps

Replace damaged semi-truck tank straps or upgrade from the original set with steel or painted tank straps made to fit all the top brands. We distribute replacement 2-inch and 4-inch fuel tank straps for tanks ranging from 16 inches in diameter up to 26 inches. Add new tank strap backing to complete the order for a new look, with standard and heavy-duty options available.

Tank Covers

Turn fuel tanks into an attractive accessory with quilted vinyl tank covers available in 20 different colors to match the exterior of a semi-truck. Fuel tank covers add style as well as a layer of protection from stones, dirt, road debris and more. Our semi-truck fuel tank covers are made for simple installation, constructed from commercial-grade vinyl and shipped in matching pairs.

Auxiliary Tanks

Reduce downtime with our selection of DOT-approved auxiliary fuel tanks, which offer 30 to 110 gallons of additional fuel storage enclosed in durable diamond-plated steel. These tanks come in a variety of sizes and styles to fit virtually any semi-truck — including those with toolboxes installed — for more range and fewer stops at the refueling station.
