Kenworth Truck Company now offers a tamper-resistant, durable, metal anti-siphoning device as standard on all Kenworth Class 8 vehicles specified with round diesel fuel tanks.
The anti-siphon device, which is on the tank filler neck, features a robust tamper-resistant heavy metal barrier that is a quarter-inch thick. The design, however, does not slow down the refueling process.
