Commercial Diesel Fuel Theft Is Getting Worse
Your Fleet Is a Target. Here's How to Stop the Bleeding.
Commercial diesel fuel theft costs US businesses over $1 billion per year. Your work trucks carry the most fuel and have the least protection. The Work Truck Fuel Vault stops diesel theft at the source — the exposed fuel filler.

Diesel Theft Is a Fleet Killer
Every stolen tank costs you fuel, downtime, emergency refueling, and schedule disruption. Multiply that across a fleet and it's a serious financial drain.
- Over $1 billion in fuel is stolen annually in the US
- Commercial trucks are the #1 target due to large, exposed fuel tanks
- Chassis cabs ship with zero fuel security from Ford or Ram
- A single theft costs $500–$1,000 including fuel and downtime
- Organized theft rings target fleet yards and jobsites
- Locking caps and cameras don't physically prevent theft
Physical Security at the Filler
Cameras watch. Caps twist off. The Fuel Vault physically blocks access. An armored locking door over the fuel filler — the only thing that actually prevents theft.
- Armored door covers the entire fuel filler — no access without a key
- Tumbler lock + security torx — tamper-resistant hardware
- Blocks siphoning, contamination, and unauthorized access
- Bolt-on in 8–15 minutes — no drilling or cutting
- Fleet-wide deployment with volume discounts
- Made in the USA with Limited Lifetime Warranty
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.
