Edelbrock 174131 Carbureted Adjustable Bypass Fuel Pressure Regulator 160 GPH Red

The Edelbrock 174131 fuel pressure regulator is precision-machined from aircraft-quality aluminum, delivering professional-grade performance for carbureted fuel systems. This adjustable bypass-style regulator is engineered to maintain consistent fuel pressure across varying flow rates, ensuring optimal engine performance and reliability.

Key Features:

• 160 GPH flow capacity for high-performance applications
• Internal fluorosilicone diaphragm provides superior high-temperature protection and extended service life
• Compatible with all grades of gasoline, ethanol, methanol, and E85 fuels
• Pressure regulation slope of 0.75 psi per gallon of flow rate change for stable operation
• Maintains fuel system pressure for at least 20 minutes after pump shutdown
• Attractive red anodized finish for underhood aesthetics
• Developed for optimum compatibility with Edelbrock electric fuel pumps
• Fully adjustable pressure settings for precise tuning

This bypass-style regulator returns excess fuel back to the tank, preventing fuel heating and vapor lock issues common in high-performance applications. The lightweight aluminum construction ensures durability without adding unnecessary weight, while the fluorosilicone diaphragm resists degradation from modern fuel formulations including alcohol-based fuels.
