Why This Truck Is a Target
- The factory cap on a Hino L7 is fully exposed — no lock, no cover.
- A medium duty build parks outside overnight where siphoning happens.
- One siphoning event costs $500 to $1,000 in fuel plus lost work hours.
- Contamination — sugar, water, dirt — can destroy an entire fuel system.

How many doors do I need for a Hino L7?
Most L7 builds need 2 doors — one for the diesel fill and one for the DEF cap. Our 2-pack and 3-pack save money versus buying singles.
Do I have to drill anything?

Will it interfere with my service body or upfit?
