GM Fuel Pressure Specifications

General Motors was originally designed as a holding company for Buick. It was founded on September 16, 1908 in Flint, Michigan. Over a period of time, GM acquired Oldsmobile, Cadillac, Elmore, Oakland --- which would later become known as Pontiac --- and others. GM acquired Reliance Motor Truck Company and Rapid Motor Vehicle Company, which would later become known as GMC Truck.
