Mainstay Fuel Technologies has begun production of a new 165-diesel-gallon-equivalent Back-of-Cab on-board compressed natural gas fuel storage and delivery system.

Using the latest generation of Type IV cylinder technology and proprietary fuel module designs, the system generates fast, more efficient fills, according to the company.

The same design and features will also be available in a 120-DGE Back-of-Cab configuration. The new systems can be paired with side-mount versions to increase or match fleet range requirements.
