Carburettor/EFI 3-Port 800hp Billet Bypass Fuel Pressure Regulator 3-60 psi Adj.

Carburettor/EFI 3-Port Billet Bypass Fuel Pressure Regulator

Upgrade your Carburettor or EFI fuel system with the Carburettor/EFI 3-Port Billet Bypass Fuel Pressure Regulator. Crafted from billet 6061‑T6 aluminum, this high‑performance regulator is engineered to support up to 800hp, delivering precise, stable fuel pressure across a range of fuels—ethanol, methanol, and unleaded. Its bypass (return) design helps minimize pressure spikes and keeps your engine fueling predictable under boost. Designed for flexible installation, it features a strategic port layout to suit diverse setups: 2 x -8 ORB inlet/outlet ports, 1 x -8 ORB return port, and 1 x 1/8" NPT pressure gauge port. This configuration provides clean routing for both carburettor and EFI systems while offering an accessible pressure gauge connection for accurate tuning.

Adjustability and range

Adjustable from 3 to 60 psi for broad tuning capability across engines and fuels. Standard spring covers 3–20 psi; an optional 20–60 psi spring is included for expanded range.
