Airtex 5G1179 Fuel Injection Pressure Regulator OEM 16740PCX003

The Airtex 5G1179 is a direct-fit fuel injection pressure regulator engineered as a reliable aftermarket replacement. Airtex fuel pressure regulators are manufactured to meet or exceed OEM specifications, ensuring proper fuel rail pressure is maintained for accurate injector operation, efficient combustion, and consistent engine performance.

The fuel injection pressure regulator controls the pressure of fuel delivered to the fuel injectors. A failed or degraded regulator can cause symptoms such as hard starting, rough idle, poor fuel economy, engine hesitation, or a rich/lean running condition. Replacing a faulty regulator restores proper fuel system pressure and protects injector performance.

Key Features:

• Direct OEM replacement — engineered to match original equipment fit, form, and function
• Constructed with high-quality materials for durability and resistance to fuel system pressures
• Helps restore proper fuel rail pressure for improved drivability and fuel efficiency
