This part cross-references Gates 22866 for the same application. The Delphi FP10477 is also referenced in fuel system interchange listings for select OE and aftermarket applications.

What It Helps Solve

• Fuel pressure that is too high or too low
• Rough idle caused by unstable fuel delivery
• Hard starting related to pressure regulation issues
• Fuel smell or rich-running symptoms from regulator failure
• Loss of drivability from inconsistent injector pressure

Installation Notes and Tips

Verify inlet and outlet port style, mounting type, and system pressure before installation. This regulator uses a push-in inlet, hose outlet, and bolt mounting arrangement, so the fuel line connections and mounting location must match the original setup. Confirm vehicle application by year, make, and model before ordering.
