Locking Fuel Doors for Texas Work Trucks
If your trucks work in Houston, San Antonio, Dallas, or anywhere else in Texas, their fuel caps are sitting completely exposed every night. The Work Truck Fuel Vault is an armored, locking fuel door that bolts over the filler area in about 15 minutes — no drilling.

Who Needs This in Texas
Texas fleets run heavy in oil, gas, and pipeline, construction and general contracting, utility and line work, landscaping and tree care. Those trucks park loaded, often outside a fenced yard, and a five-gallon can walks off with your fuel before sunrise.

Is diesel theft a real problem in Texas?
Fuel theft follows work. Texas runs heavy in oil, gas, and pipeline, construction and general contracting, utility and line work, landscaping and tree care — the exact industries whose trucks sit loaded overnight at yards, jobsites, and lots. That is where siphoning happens.
