NEW HERKO 4 Bar Fuel Pressure Regulator FG FGX Falcon Barra NA+T E85 FPR PR4127

NEW HERKO 4 Bar Fuel Pressure Regulator FG FGX Falcon Barra NA+T E85 FPR PR4127

This is a simple way to increase fuel system capacity while retaining the factory fuel rail and injectors. Manufactured by Herko, this 4 Bar / 400kPa regulator clips directly into the factory FG and FGX naturally aspirated Barra fuel rail with the plastic intake manifold.

By increasing fuel pressure by approximately 33% over the factory regulator, this upgrade allows the standard injectors to deliver increased fuel flow, making it ideal for NA+T Barra conversions, E85 setups, and other higher-demand applications.
