High-Flow Low Pressure Fuel Regulator for Carbureted Engines

The GFB FX-D Low Pressure Fuel Regulator is engineered for carbureted fuel systems that operate at significantly lower pressures than EFI systems. It provides stable and consistent fuel pressure control, which is critical for correct carburetor operation and engine reliability.

Designed for Carbureted Fuel Systems

Carburetors require low and stable fuel pressure to maintain correct float bowl levels and metering. The FX-D regulator is built specifically for this purpose and is not intended to replace high-pressure EFI regulators.

High-Flow -8AN Port Design

Featuring -8AN inlet and outlet ports, the FX-D regulator supports high fuel flow for modified and high-output carbureted engines, where smaller regulators may become restrictive.

Precise Adjustable Pressure Control

Fuel pressure is fully adjustable, allowing fine tuning to suit different carburetor types, engine combinations and fuel pump setups.

Performance-Oriented Construction

Designed for demanding street and motorsport environments, the FX-D regulator offers reliable pressure control under varying load and operating conditions.
