No Hatch. No Door. No Protection.
The fuel filler on chassis cab trucks is wide open. No hatch, no door, no cover — just a naked cap.
- Chassis cab trucks have no factory fuel tank hatch or door
- The fuel filler cap is completely exposed and accessible
- Thieves siphon fuel, contaminate tanks, and cost you money
- No OEM option exists to add fuel filler protection
- Locking caps provide minimal security against determined thieves
- Fleet fuel shrinkage adds up to thousands per year
The Fuel Tank Hatch That Locks
The Work Truck Fuel Vault adds a real locking hatch over the fuel filler area. Armored, bolt-on, and done in 15 minutes.
- Armored hatch covers the fuel filler area — cap, neck, and access point
- Tumbler lock + security torx fasteners — tamper-resistant
- UV-stable composite for years of outdoor use
- Bolt-on in 8–15 minutes — no drilling or cutting
- Fits Ford and Ram chassis cabs with any body type
- Made in the USA — Sarasota, Florida
The Part The Factory Forgot
The Work Truck Fuel Vault is an armored, locking fuel door that covers the entire fuel access area on your work truck. No more exposed caps. No more easy targets.
Why Didn't This Exist Before?
Despite billions lost to fuel theft every year, nobody built a real solution for commercial work trucks. Here's why.
"Good Enough" Thinking
The industry defaulted to cheap aftermarket locking gas caps. A $15 key-locked cap was considered good enough — until thieves proved otherwise with a pair of pliers.
Upfitters Focus on the Body, Not the Cap
Manufacturers like Knapheide and Reading engineer every compartment lock on the service body — but the chassis fuel pocket belongs to Ford or Ram. Nobody owned the gap.
The Zero-Drill Engineering Problem
Consumer billet doors are made for flat pickup beds. The recessed fuel pocket on a commercial chassis is a completely different geometry — and drilling risks voiding the chassis warranty.
The Cost Was Just "Absorbed"
Fleets treated fuel theft like weather damage. A $500 siphoning hit got buried in operating expenses. Without a purpose-built product available, the problem was simply accepted.
The Work Truck Fuel Vault is the industry's first drop-in armored fuel door that uses existing factory mounting points. No drilling. No cutting. No warranty risk.

Frequently Asked Questions
What is a fuel tank hatch?
A fuel tank hatch covers the fuel filler access point on the vehicle. The Fuel Vault mounts over the fuel filler area near the cab — not on the tank itself — providing full locking protection.
Does it mount on the fuel tank?
No. The Fuel Vault mounts at the fuel filler neck area, between the cab and the body. It covers the access point where you insert the fuel nozzle.
What trucks does it fit?
Ford F-550, F-600, E-350, E-450, and Ram 5500 chassis cabs.
Does it require drilling?
No. Bolt-on install in 8–15 minutes with basic hand tools.
Does it lock?
Yes — tumbler lock with security torx fasteners.
