M+A is responsible for developing and maintaining Circle K national retail fuel system prototypes. M+A meets on a regular basis with Circle K regional managers and petroleum system equipment vendors to develop and maintain these prototypes.

As part of the project, M+A has developed options for fiberglass Underground Storage Tanks (USTs), Fiberglass-clad Steel USTs, fiberglass piping, flexible piping, high-speed diesel, Diesel Exhaust Fluid (DEF) systems, California-specific requirements, and future fuels. Fuel electrical and controls are included in these prototypes.

M+A has site adapted these prototypes for Circle K at hundreds of locations across the United States.
