Mainstay Fuel Technologies and Fontaine Modification reached an agreement to provide a turnkey process for the delivery and installation of compressed natural gas fuel systems on Class 8 heavy-duty, over-the-road tractors.

Fontaine will install the back-of-cab and side-saddle CNG fuel storage, management, and delivery systems made by Mainstay. The back-of-cab and side-saddle configurations are available from 30-220 DGE, or diesel gallon equivalents, so various fleet range requirements can be met.

The installations will be made at Fontaine’s centers in the U.S.
