American Honda Motor Co., Inc., which markets the Civic GX natural gas vehicle, has purchased a 20 percent interest in FuelMaker Corporation, a privately held Toronto-based company and the leading manufacturer of natural gas vehicle refueling appliances. In addition, Honda R&D Americas, Inc., will provide market research information to assist FuelMaker's efforts in developing an inexpensive, advanced technology, home refueling appliance for natural gas vehicles. This new product will allow natural gas powered vehicles to be conveniently refueled from a homeowner's natural gas line, in addition to refueling at public stations.
