Detailed Description

Built from Delphi’s OE heritage and supplier experience, the FP10384 is engineered to maintain consistent fuel pressure in the injection system. This fuel injection pressure regulator is a direct replacement for the Porsche Cayenne application listed above, and its metal body, push-in inlet, and returnless outlet layout match the needs of the original fuel delivery setup. The Delphi FP10384 is also referenced by cross numbers including Gates 24135 and 24144 for the same application.

Common Issues It Can Address

• Fuel pressure that is too high or too low
• Hard starting caused by unstable fuel delivery
• Rough idle related to pressure regulation problems
• Fuel system performance issues on a returnless setup
• Replacement needs on a 2003-2006 Porsche Cayenne with Auxiliary Heater

Installation Notes and Tips

Verify the inlet port diameter, push-in connection, clamp mounting style, and returnless outlet configuration before installation. Confirm vehicle application by year, make, model, and Auxiliary Heater note for the Porsche Cayenne. Inspect surrounding fuel system components during service to ensure the replacement regulator is installed into a clean, properly sealed connection point.

Quality Assurance

Delphi draws on more than 100 years of OE experience and knowledge developed through supplying major automakers. That OE background is reflected in the FP10384 fuel pressure regulator’s construction and application-specific design for the Porsche Cayenne fuel system.
