Standard Ignition Fuel Injection Pressure Regulator P/N:PR46
Standard Ignition PR511 fuel injection pressure regulator for the 2003-2009 Dodge Ram 2500 6-cylinder 5.9L and other vehicles controls the fuel pressure in the injection system.
A worn regulator can show up as hard starting, a rough idle or uneven power. Fuel injectors, a weak fuel pump or a clogged fuel filter can be behind those signs too, so find the cause before buying a new regulator. The engine takes one regulator.
This regulator is a direct-fit replacement for the 2003-2009 Dodge Ram 2500 6-cylinder 5.9L and the 2003-2007 Dodge Ram 3500 6-cylinder 5.9L.
