Stop Fuel Theft on HVAC & Plumbing Fleets
HVAC and plumbing service fleets take trucks home with the techs, park them on the street, in apartment lots, and outside supply houses — anywhere a siphon hose can reach after dark. A stolen tank overnight means a tech starts the route late and a customer window gets missed. The Work Truck Fuel Vault locks down the fuel cap so a take-home truck stays ready for the first call.
Why HVAC & plumbing fleets get hit
- Take-home trucks parked overnight on public streets and in shared lots.
- Service-body chassis cabs with the fuel cap left exposed by the upfit.
- A siphoned tank pushes the first appointment late and burns customer goodwill.
- High truck visibility with brand wraps also flags a full fuel tank to thieves.
How the Fuel Vault protects
- Keyed locking door keeps take-home trucks ready for the first call of the day.
- Installs in minutes — no downtime pulling trucks off the schedule.
- Retains the clean factory-finished look on branded, customer-facing trucks.
- One key system can be standardized across the whole service fleet.
Real-World Fleet Results
Fuel loss dropped to near zero across the yard
A regional public-works fleet outfitted 30-plus F-550 and Ram 5500 chassis after repeated overnight siphoning at an unsecured lot. Reported fuel shrinkage fell off almost immediately after the bolt-on doors went on.
Stopped repeat siphoning at remote job sites
A utility contractor running trucks parked at remote and unsecured sites installed doors fleet-wide. The exposed fuel and DEF caps were the weak point — once covered, the repeat losses stopped.
Paid for itself inside the first month
A grading contractor lost several hundred dollars of diesel from a single truck before protecting the fleet. At roughly the cost of one tank of stolen fuel per truck, the doors paid back fast.
Added as a standard buildout upgrade
A service-body upfitter now offers the locking fuel door as a visible security line item during buildout, giving fleet buyers a factory-finished theft deterrent from day one.

Frequently Asked Questions
Our techs take trucks home — does that make theft harder to prevent?+
That is exactly the case the Fuel Vault is built for. Take-home trucks park wherever the tech lives — streets, apartment lots, driveways — with no yard security at all. A keyed locking fuel door protects the truck no matter where it sits overnight, so it is ready for the first call.
Does it look right on a branded, customer-facing truck?+
Yes. It bolts on over the filler area and retains a clean, factory-finished look, so it does not clash with your wrap or branding. It reads as a professional upgrade, not a bolt-on afterthought.
Can we key the whole fleet alike?+
Talk to our fleet team about keying so your service fleet is simple for techs to operate. Share your truck count and chassis mix and we will put together a fleet quote.
