Go Fast Bits FX-R Fuel Pressure Regulator with -6AN Ports
The Go Fast Bits (GFB) FX-R Fuel Pressure Regulator is built for serious performance applications, delivering precision fuel control, high flow capacity, and OEM-like reliability. Engineered with advanced features and durable materials, the FX-R is suitable for a wide range of fuels including unleaded, ethanol, methanol, and diesel.
With 2x -6AN inlet ports, 2x 1/8” NPT gauge/sensor ports, and 1x -6AN return port, this regulator flows up to 1300 LPH at 25 PSI and supports everything from single pump setups to high-output triple pump systems. The 1:1 fuel pressure rise rate ensures consistent performance under boost, while the adjustable static pressure range of 25–80 PSI allows flexibility for different builds.
Unlike conventional regulators that rely on metal-to-metal sealing, the FX-R features a replaceable Teflon co-polymer seat with a stainless valve, delivering factory-like sealing to hold fuel pressure after shutdown for easier startups. Reinforced double-layer diaphragms with a burst strength over 500 PSI provide maximum safety and durability.
Proudly engineered by GFB, the FX-R is completely serviceable and designed to handle the demands of modern high-performance engines.
