Detailed Description

Delphi FP10628 is a fuel injection pressure regulator engineered for select Toyota Tacoma models. It is designed with one inlet and one outlet, a push-in inlet type, and a hose-style outlet to align with the factory fuel delivery arrangement. The metal housing supports consistent operation in the fuel system, while the non-adjustable design keeps pressure control fixed at the specified 41 system pressure.

Delphi draws on long OE experience and supplier knowledge from original equipment development, which is reflected in the fit and function of this replacement part. If you are servicing a 2012 Toyota Tacoma from 10/2011 or a 2013-2015 Toyota Tacoma, FP10628 provides a direct replacement path for the factory fuel injection pressure regulator. This part cross-references Standard Ignition PR539 for the same application.

Common Issues This Part Addresses

• Fuel pressure that is outside the specified range
• Rough idle caused by inconsistent fuel delivery
• Hard starting related to regulator performance
• Fuel system drivability concerns on Tacoma applications
• Pressure control problems in the injection system

Installation Notes and Tips

Confirm the vehicle application before installation, especially on 2012 Toyota Tacoma models built from 10/2011. Verify the inlet and outlet style, mounting method, and system pressure specification against the original part before replacement. Inspect fuel lines and sealing surfaces during service to help ensure proper fitment and operation.

Quality Assurance

Delphi builds aftermarket parts using OE experience and original equipment knowledge developed through work with major automakers. FP10628 is manufactured to support factory-style fuel system service on the listed Toyota Tacoma applications.
