Momentum Fuel Technologies' 115 diesel gallon equivalent tailgate system is a compressed natural gas fuel system solution for Class 6-8 trucks.

The tailgate system was designed for E-Z Pack, who had previously used five- and six-tank tailgate systems on its refuse bodies. Momentum was able to produce a system that increased capacity while reducing the number of tanks to three.

The system is 400 pounds lighter than E-Z Pack’s previous system and is designed to be scalable, with a smaller, two-tank 75DGE system available as well.

With safety and convenience in mind, the system features a visible pressure gauge so drivers and technicians can see the pressure in the tank from ground level. The system’s tanks are at least seven feet off the ground with a steel guard structure around the base, designed to be safer in the event of a rear impact.  Further, the tailgate system keeps a lower profile than other CNG configurations, for improved safety in refuse vehicles.

All E-Z Pack units include a vertical fuel management module (FMM), which houses the electronics, fuel filter and fuel-fill receptacles and works in conjunction with the Rush Truck Centers’ telematics platform, allowing fleet managers to monitor usage and manage fuel consumption.  The vertical FMM is narrower than the version used in other Momentum configurations, taking up less valuable space on smaller truck bodies.
