The FX-S Series fuel pressure regulators from Go Fast Bits join their existing line of successful fuel delivery products—built with the same precision, machining quality, and reliability that is the foundation of GFB's reputation. Go Fast Bits FX-S fuel pressure regulators are available in different model configurations to meet the needs of your specific setup. The 8050 models have multiple inlet/gauge ports that allow for a wide range of fuel system setups beyond the usual inlet/outlet, including parallel fuel rail or returnless "deadhead" systems. The two gauge ports allow you to run a mechanical fuel pressure gauge and an ECU fuel pressure sensor if you want. GFB also offers the 8051 model—a direct drop-in Bosch replacement for common Bosch regulators that clip into the fuel rail, rather than replacing the entire fuel rail or using an adaptor with a separate fuel pressure regulator. By simply clipping in the FX-S 8051 fuel pressure regulator will allow you to run a much larger pump setup even with the factory rail. Whether you run pump petrol/gasoline, Ethanol, Methanol or Diesel—Go Fast Bits has you covered—no matter what your fuel pressure regulatory requirements are! Features of FX-S Series fuel pressure regulators: * Billet aluminum construction with black anodized finish * Features double-layer diaphragm that has twice the reinforcing material of the single layer type used in most regulators * Valve seat has a soft, more compliant yet resilient material that positively seals and holds fuel pressure for easier startup vs. conventional aftermarket fuel pressure regulators that utilize metal-to-metal valve and seat * PTFE co-polymer seat with spherical stainless valve retains fuel pressure longer after shutdown * Spring pre-load adjustment screw is O-ring sealed and does not leak vacuum/boost * Completely serviceable
