4-Port Bypass Adjustable Regulator - 3-15psi

The 4-Port Bypass Adjustable Regulator - 3-15psi by Aeromotive is essential for any serious fuel system tuning project, whether for a street machine, race car, or high-performance daily driver. This regulator addresses the critical need for maintaining precise fuel pressure across varying engine loads and RPM ranges.

As fuel demand rises during acceleration or sustained high RPM, both carbureted and fuel-injected systems require dynamic pressure control to avoid issues like flooding and vapor lock. The bypass design efficiently returns excess fuel to the tank, preventing heat buildup in the fuel lines. With an adjustable range from 3 to 15 psi, this regulator allows fine-tuning for various applications.

The four-port configuration facilitates simultaneous connections for fuel supply, return, inlet gauge, and vent ports, enhancing system diagnostics and flow management. This regulator is particularly beneficial for those looking to optimize performance in both carbureted and fuel-injected engines.
