Why This Truck Is a Target
- The factory cap on a Ford F-250 is fully exposed — no lock, no cover.
- A pickup 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.

Ford F-250 Super Duty — Common Questions
Does the Work Truck Fuel Vault fit a 2017–2026 Ford F-250 Super Duty?
Yes. The F-250 Super Duty uses recessed filler neck with exposed cap. The recommended fit is the Small Fuel Vault door. Pickup beds with factory doors do not need the Vault; flatbed conversions do.
How many doors do I need for a Ford F-250 Super Duty?
One door covers a standard F-250 Super Duty. 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 pickup build.
What is the warranty?
