A Bolt-On Upfit Line Item for NTEA Members
NTEA members build, upfit, and sell the work trucks America runs on. The Work Truck Fuel Vault is an easy add-on for Ford and Ram chassis-cab builds: armored, keyed, and installed in 8–15 minutes at the end of upfit or at PDI, with no drilling into the body.
What your fleet customers are asking for
- Fuel theft protection on new units from day one
- Exposed fuel and DEF caps on service, utility, and dump bodies
- An accessory that doesn’t complicate body installation or warranties
- Higher-margin add-ons for fleet bids and stock units
The fix: lock the fill
The Work Truck Fuel Vault is an armored, keyed door that covers the entire fuel filler, cap and neck, on Ford F-350–F-600, E-Series, and Ram 3500–5500 chassis cabs. It blocks siphon hoses, pry bars, and contamination, and bolts on in 8–15 minutes with no drilling. Made in Sarasota, Florida. Patent pending. From $139.95.
Why upfitters and distributors add it
No body modification
Mounts over the filler area with hand tools, with no cutting or drilling.
Fast install
8–15 minutes, so it fits at the end of upfit or during PDI.
Wholesale program
Dealer, distributor, and body-builder pricing through our partner program.
Broad chassis coverage
Ford F-350–F-600, E-Series cutaways, and Ram 3500–5500 chassis cabs.
What Fleets See
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.
Illustrative, industry-representative scenarios. Individual results vary by fleet and operating conditions.
