Delphi Fuel Injection Pressure Regulator P/N:FP10703
Delphi FP10384 fuel injection pressure regulator for the 2003-2006 Porsche Cayenne V8 4.5L and the 2004-2006 Cayenne V6 3.2L regulates the fuel pressure delivered to the injectors.
Hard starting, rough running or a fuel smell can mean the regulator is failing. Before you replace it, rule out a weak fuel pump, a clogged fuel filter and leaking injectors, since they can show up the same way; a shop can test fuel pressure to sort it out.
This regulator fits the 2003-2006 Porsche Cayenne V8 4.5L and the 2004-2006 Porsche Cayenne V6 3.2L. The listing is one regulator, and each engine takes a single one.
