Precision Fit for the F-550
Our locking fuel door is engineered specifically for the Ford F-550 chassis. No universal adapters, no shimming, no guesswork. The Military Fuel Vault drops into place on your F-550 with a precise fit that matches the body lines and looks like it came from the factory.
Common F-550 Applications
The Ford F-550 serves as the platform for ambulances, utility trucks, service bodies, flatbeds, and many other government and military applications. Whether your F-550 is a bare chassis cab or a fully upfitted specialty vehicle, our locking fuel door fits and works perfectly.
Quick Installation
Installation takes under 30 minutes with basic hand tools. No drilling into the body, no cutting, no welding. The fuel door mounts securely using the existing fuel filler assembly. Your fleet mechanic can install these during routine maintenance without any special training.
