GFB FX-S Bosch Fuel Pressure Regulator Adjustable 1.4bar to 5bar Performance Upgrade

This component is essential for maintaining optimal fuel delivery in high-performance engines. It is designed to handle the increased demands of larger fuel pumps, particularly in turbocharged setups utilizing E85 fuel. By replacing the factory regulator, this product prevents excessive fuel pressure, especially during idle conditions, which can lead to engine performance issues.

Installation is straightforward, allowing for the use of an upgraded fuel pump while retaining the factory fuel rail. The adjustable pressure range from 1.4 bar to 5 bar accommodates various tuning requirements, providing flexibility as performance needs change.

Built with reliability in mind, it features a soft Teflon valve seat that ensures a positive seal, minimizing the risk of leaks and ensuring consistent fuel pressure for dependable engine starts. The robust double-layer diaphragm boasts a burst strength exceeding 1000 psi, significantly enhancing durability compared to standard single-layer options.

Additionally, the integrated 1/8" NPT port allows for easy connection of a fuel pressure gauge or electronic pressure sensor, making monitoring fuel pressure more accessible.
