Why This Truck Is a Target
- The factory cap on a Ford F-550 is fully exposed — no lock, no cover.
- A wildland 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.

E-ONE (Emergency One) Brush Truck — Common Questions
Does the Work Truck Fuel Vault fit a 2010–2026 E-ONE (Emergency One) Brush Truck?
Yes. The Brush Truck uses exposed threaded fuel cap, no factory door. The recommended fit is the Small Fuel Vault door. Remote deployment — high exposure.
How many doors do I need for a E-ONE (Emergency One) Brush Truck?
One door covers a standard Brush Truck. 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 wildland build.
