Standard Motor Products PR473 Intermotor Fuel Injection Pressure Regulator

The Standard Motor Products PR473 is an Intermotor fuel injection pressure regulator engineered as a direct-fit OE replacement for vehicles with failed or degraded fuel pressure regulation. The fuel pressure regulator plays a critical role in the fuel delivery system, maintaining consistent fuel pressure to ensure that injectors receive and dispense fuel at the correct rate for the engine's varying demands.

Key Features:

• Direct-fit OE replacement — engineered for proper fit, form, and function with no modifications required
• High-grade steel construction — resists corrosion and withstands harsh under-hood conditions
• High-temp Viton O-rings — provide a reliable high-pressure seal even under extreme heat conditions
• Designed and manufactured to stringent quality standards — undergoes extensive testing and validation for consistent performance and peak reliability
• Precise fuel pressure control — ensures optimum fuel metering for best possible fuel economy and engine performance

A failing fuel pressure regulator can cause hard starting, rough idle, stalling, poor fuel economy, and reduced acceleration. Replacing it with the Standard Motor Products PR473 restores proper fuel system function and protects injectors from damage caused by incorrect fuel pressure. The Intermotor line is trusted by professional technicians and DIYers alike for quality and reliability.
