Back-of-cab CNG fuel systems
Our ProCab® CNG fuel systems are installed behind the cab and are available in a range of sizes from 60 diesel gallon equivalent (DGE) to 175 DGE.
Our 175 DGE ProCab fuel system allows up to 700 mile range before re-fueling. ProCab can be combined with our ProRail® side-mount systems for a maximum of 295 DGE, allowing over 1,200 mile range before re-fueling.
Our ProCab fuel system has over 1 million miles in the field, is made of aircraft-grade aluminum, and is mounted on rubber isolators to reduce stress on components.
Patented Drive-Away-Protection system disconnects ignition circuit when fuel caps are not in place or fill panel door is ajar. Integrated pressure relief devices for fire safety.
