Fuel Pressure Regulator Bypass Style 180GPH Red

The Fuel Pressure Regulator Bypass Style 180GPH Red from Edelbrock is a precision fuel system component engineered for carbureted and fuel-injected applications requiring reliable pressure control and fuel return capability. This regulator is ideal for engine builders, hot rodders, and performance enthusiasts who need to maintain consistent fuel delivery across 5 to 10 psi operating range. The 180 gallons per hour flow capacity accommodates high-performance engine demands while the bypass design protects fuel pumps and carburetors from excessive pressure spikes.

Built from anodized aluminum in a distinctive red and clear finish, this regulator features 10 AN female O-ring inlet connections, 10 AN female O-ring outlet, and 6 AN female O-ring return line port for flexible fuel line routing. The integrated 1/8 inch NPT port accommodates a fuel pressure gauge for real-time monitoring, allowing tuners to dial in optimal fuel pressure for peak engine performance. The bypass valve design automatically relieves excess fuel back to the tank, preventing pressure buildup that could damage injectors or carburetors—a critical safety feature for street and race applications.

This regulator excels in multi-fuel environments, supporting gasoline, E85 ethanol blends, and methanol fuel systems without degradation. Installation works as an in-line component in standard fuel distribution systems, making it compatible with most carburetor and fuel-injection setups. Its compact 4 x 3 x 4.7 inch footprint and lightweight 1 lb construction enable discreet engine bay mounting, while the industry-standard AN fittings ensure straightforward integration with existing fuel lines and custom fuel systems.
