Why This Truck Is a Target

  • The factory cap on a Ford E-450, Chevrolet Express 4500 is fully exposed — no lock, no cover.
  • A shuttle bus build parks outside overnight where siphoning happens.
  • One siphoning event costs $500 to $1,000 in fuel plus lost work hours.
  • Contamination — sugar, water, dirt — can destroy an entire fuel system.

Collins Bus NexBusCommon Questions

Does the Work Truck Fuel Vault fit a 2014–2026 Collins Bus NexBus?

Yes. The NexBus uses exposed threaded fuel cap, no factory door. The recommended fit is the Small or Large Fuel Vault door. Confirm bezel size.

How many doors do I need for a Collins Bus NexBus?

One door covers a standard NexBus. If your truck has a separate exposed DEF cap, add a second door.

Do I have to drill anything?

No. The Fuel Vault bolts on using the existing filler area. No drilling, no cutting, no welding. Basic hand tools, about 15 minutes.

Will it interfere with my service body or upfit?

The Fuel Vault mounts to the chassis fuel filler area, not the body. It does not interfere with compartments, shelving, cranes, or racks on a shuttle bus build.

What is the warranty?

Limited lifetime warranty on the hardware, plus a 30-day money-back guarantee. Free shipping within the United States.
