Keep fuel-rail pressure steady with the Standard Ignition Fuel Injection Pressure Regulator (PR6). A fuel pressure regulator meters the pressure the injectors see, so fuel is delivered at the correct pressure as engine load and throttle demand change. It installs as a direct-fit replacement for a range of 1980-1987 Ford, Lincoln, and Mercury applications running the V6-3.8L or V8-5.0L engines.
- Consistent fuel delivery: helps maintain precise fuel pressure across changing engine load and throttle conditions.
- Sealing & heat handling: seals and thermal resistance designed for reliable operation across driving conditions.
- Validated design: engineered through 200+ hours of vibration testing, 1000+ hours of extreme heat and cold operational testing, plus on-vehicle testing.
- Durable materials: built from corrosion-resistant, high-durability materials to resist wear and deformation.
If a failed regulator is the cause of a rough idle, hard starting, or a fuel-pressure fault, this PR6 replaces it. Country of origin: Mexico.
