Delphi FP10536 Fuel Injection Pressure Regulator

Fuel Pressure Control for Honda Applications

The Delphi FP10536 fuel injection pressure regulator is built for precise fuel system control in select Honda applications. It uses a metal body, a push-in inlet, and a hose outlet to support stable fuel pressure at 44 psi.

Compatible with 2003-2005 Honda Civic with California Emission System and 2006-2007 Honda Accord with California Emission System, this regulator is a direct-fit service part for the listed applications. Delphi draws on OE engineering experience used by major automakers, and that background is reflected in the design of this aftermarket component.

Key Features

• Delphi FP10536 fuel injection pressure regulator
• Metal construction for fuel system durability
• Push-in inlet and hose outlet configuration
• Bolt-mounted design for secure installation
• Fixed system pressure rating of 44 psi
• No gauge port and non-adjustable design
• Fits Honda Civic and Honda Accord California Emission System applications

Detailed Product Overview

The FP10536 is a fuel injection pressure regulator designed to maintain consistent fuel delivery in the specified Honda fuel system applications. Its 1 inlet and 1 outlet layout, along with the push-in inlet and hose-style outlet, supports the original equipment-style plumbing used on the listed vehicles. If you are replacing a worn regulator on a 2003-2005 Honda Civic or a 2006-2007 Honda Accord, Delphi FP10536 provides the correct pressure control specification for those California Emission System configurations.

This part cross-references Standard Ignition PR372 for the same application.

Common Issues This Part Can Address

• Fuel pressure that is too high or too low for the engine calibration
• Hard starting caused by unstable fuel delivery
• Rough idle related to inconsistent injector pressure
• Fuel odor or drivability concerns tied to regulator wear
• Loss of throttle response from improper fuel pressure control

Installation Notes and Tips

Confirm the vehicle is equipped with the California Emission System before ordering. Match the inlet and outlet styles, mounting method, and pressure specification to the original part before installation. Inspect fuel lines and sealing surfaces during replacement, and verify there are no leaks after the system is reassembled.

Quality Assurance

Delphi builds aftermarket parts using more than a century of OE experience and supplier knowledge from working with major automakers. That OE heritage informs the design and fit of the FP10536 for the listed Honda applications.
