Go Fast Bits FX-R Fuel Pressure Regulators

If you're looking for an EFI fuel pressure regulator that seals and behaves just like your factory unit but with the added reliability and high flowing capacity you require, check out Go Fast Bits FX-R Series fuel pressure regulators. The multiple inlet/gauge ports 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 to. GFB's engineers incorporated a softer, more compliant yet resilient material for the valve seat that positively seal and hold the fuel pressure on shut down for factory-like sealing and reliable startup, as well as superior fuel resistance suitable for Unleaded, Ethanol, Methanol, and Diesel fuels. Whether you run pump petrol/gasoline, Ethanol, Methanol or Diesel, a single small pump, or a massive triple setup, the Go Fast Bits FX Series EFI fuel pressure regulators range has got you covered, no matter what your fuel pressure regulatory requirements are! Additional features and benefits: * Billet aluminum construction with black anodized finish * Double-layer/double reinforced diaphragms have 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 Show Less
