Standard Motor Products PR435 Intermotor Fuel Injection Pressure Regulator

The Standard Motor Products PR435 is a new (not remanufactured) fuel injection pressure regulator engineered under the Intermotor brand for precise fuel delivery and reliable engine performance. Designed as a direct OE replacement, this regulator maintains the correct fuel pressure to the injectors, ensuring an accurate air/fuel mixture under all driving conditions.

Key Features:

• Precision-engineered for stock fuel pressure output — no adjustment required
• Vacuum/boost reference port for accurate load-based pressure compensation
• Application-specific design ensures proper fit and form
• Robust construction for enhanced resistance to leakage
• 100% new components — no remanufactured parts
• Engineered to address known OE failure points for lasting reliability
• Subjected to rigorous testing including flow analysis, durability, vibration, and thermal cycling validation

Cross-Reference Part Numbers:

• Airtex: 5G1270

A faulty fuel pressure regulator can cause excessive fuel pressure, leading to an overly rich air/fuel mixture, poor fuel economy, and reduced performance. If the regulator diaphragm fails, fuel can be drawn into the intake manifold through the vacuum hose, further compounding drivability issues. The Standard Motor Products PR435 restores proper fuel system operation and protects against these common failure modes.
