Low-Speed Bypass Model H - Buna-n Diaphragm

The Low-Speed Bypass Model H - Buna-N Diaphragm is a precision fuel system component designed for vehicles utilizing custom fuel injection setups, superchargers, and forced induction platforms. This bypass regulator is essential for maintaining reliable fuel pressure regulation, particularly in high-performance applications.

Constructed with a Buna-N diaphragm, this regulator is durable and resistant to degradation from modern ethanol-blend fuels. Its low-speed bypass design allows for precise flow control at idle and cruise conditions, effectively preventing fuel starvation while venting excess pressure back to the tank.

Ideal for mechanics and engine builders, this regulator is compatible with both carbureted and fuel-injected engines, making it suitable for a range of applications from street machines to race cars. Its compact size and lightweight design facilitate easy integration into tight engine bays.
