Standard Ignition Fuel Injection Pressure Regulator P/N:PR539
Standard Ignition PR488 fuel injection pressure regulator for the 1998-1999 Dodge Durango V6 3.9L, the 1998-2000 Durango V8 5.2L, the 1998-2003 Durango V8 5.9L and the 2000-2003 Durango V8 4.7L regulates the fuel pressure that reaches the injectors to help keep fuel delivery consistent.
A regulator that is failing can show up as hard starting, a rough idle or a fuel smell. These signs alone do not prove the regulator is at fault, since a clogged fuel filter is another common source of them.
This regulator fits the 1998-1999 Dodge Durango V6 3.9L, the 1998-2000 Durango V8 5.2L, the 1998-2003 Durango V8 5.9L and the 2000-2003 Durango V8 4.7L. A Durango takes a single regulator, whichever of these engines it has.
