Technical Details and Specifications

The FP10455 fuel injection pressure regulator by Delphi is engineered to maintain a steady fuel pressure of 58 psi within the fuel injection system of Mazda Miata vehicles. Featuring a metal construction, it offers resistance to wear and corrosion. The inlet port uses a push-in connection with a diameter of 0.43 inches (11.0 mm), while the outlet port is designed for hose attachment with a diameter of 0.31 inches (8.0 mm). This regulator includes one inlet and one outlet port, and it mounts securely using bolts, ensuring a stable fit within the fuel delivery system. The non-adjustable design simplifies installation and maintains factory specifications without the need for manual tuning.

Applications and Problem Resolution

This fuel injection pressure regulator is intended for use in the fuel injection system of Mazda Miata models. It helps regulate fuel pressure to ensure consistent engine performance and fuel efficiency. Common issues addressed by this part include:

• Fluctuating or inconsistent fuel pressure
• Engine hesitation or stalling due to improper fuel delivery
• Fuel leaks caused by worn or damaged regulators
• Poor fuel economy related to pressure irregularities
• Check engine light triggered by fuel system faults

Installation Notes and Tips

When installing the Delphi FP10455 fuel injection pressure regulator, ensure the vehicle is cool and the fuel system is depressurized to avoid fuel spray. The bolt mounting type requires proper torque to secure the regulator without damaging the mounting points. Verify that the push-in inlet and hose outlet connections are properly seated and free of debris to prevent leaks. Since this regulator is non-adjustable, no pressure tuning is necessary after installation. Always consult the Mazda Miata service manual for specific installation procedures and safety precautions.
