GM Fuel Pressure Specifications
by Keith Owings
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. Fuel pressure specifications may vary from one vehicle to the next due to the difference in engine specifications.
