Abstract
In one embodiment of the present invention, a 'returnless' fuel delivery system for a motor vehicle includes a fuel pressure regulator located in the fuel tank and a fuel pressure damper located at the fuel rail on the vehicle's engine. The fuel return line from the fuel rail to the fuel tank, a conventional feature in fuel delivery systems, is eliminated. Fuel delivery systems according to the present invention can provide very precise fuel delivery at a highly competitive system cost.
