Diesel Theft Prevention for Emergency Apparatus
Diesel theft from heavy vehicles is a volume crime. A rig with a large tank and an unlocked fill panel is a better target than a passenger car, and emergency apparatus are parked in predictable places on predictable schedules.
Why It Happens
Siphoning needs seconds, not tools
If the fill is reachable and uncovered, the only thing standing between a tank and a hose is a plastic panel that swings open by hand.
Big tanks are worth the trip
Apparatus tanks hold far more than a pickup, which makes a single visit worth more to a thief and more costly to the department.
The damage outlasts the fuel
Beyond the fuel itself, a compromised fill can mean contamination, a tank drop and a rig out of the run order.

Common Questions
Does a locking gas cap do the same thing?
A locking cap protects the cap. It leaves the fill neck and the surrounding area exposed, and the factory door still opens freely. A locking door closes the whole opening.
Will this stop a determined thief with tools?
No lock is absolute. The point is to remove the easy, silent, seconds-long opportunity that an unlocked plastic door creates.
Where do I start?
Confirm your chassis in the fit finder, then request a quote with the number of fills per rig.
