Dorman - OE Solutions Fuel Injection Pressure Regulator P/N:904-239
Dorman 904-573 fuel injection pressure regulator for the 2003-2009 Dodge Ram 2500 6-cylinder 5.9L and other vehicles controls fuel pressure in the injection system.
Hard starting, rough running or uneven fuel economy can mean a regulator problem, though other fuel-system faults produce the same symptoms. With the engine off and cool, look over the regulator and its connections for cracks, damage or fuel wetness; a pressure test is a job for a shop.
This regulator is a direct replacement for the 2003-2009 Dodge Ram 2500 6-cylinder 5.9L, the 2003-2008 Dodge Ram 3500 6-cylinder 5.9L and the 2005-2009 Dodge Ram 4000 6-cylinder 5.9L, with one regulator per vehicle.
