GFB FX EFI fuel pressure regulators are designed to provide a high-performance, reliable, and durable solution for a variety of applications, including gasoline, ethanol, methanol, and diesel. These regulators provide precise fuel pressure control and are suitable for system configurations ranging from a single pump to more complex systems with multiple pumps.
GFB FX regulators are ideal for high performance engines requiring stable and reliable fuel flow, as well as those using alternative fuels such as ethanol or methanol.
Installation flexibility with multiple ports allows for customization of the fuel system configuration to meet specific vehicle needs.
Durable materials and careful design ensure optimum longevity and performance, even under high pressure and temperature conditions.
Unlike many conventional fuel pressure regulators that use metal-to-metal seats, the GFB FX's unique design includes a replaceable copolymer valve seat, which seals better and retains fuel pressure at shutdown, providing more reliable starts.
Double-reinforced diaphragms provide superior durability over traditional regulators, minimizing the risk of failure in high pressure environments.
Multiple Ports for Increased Flexibility: Equipped with 4 1/8" NPT ports for fuel inlets, pressure gauges or ECU sensors, and one 1/8" NPT return port, providing flexibility in fuel system configuration.
These multiple ports also allow the use of parallel or returnless ("deadhead") fuel rail systems, and the connection of both a mechanical pressure gauge and an ECU pressure sensor if required.
High and Adjustable Flow Rate: This regulator provides a flow rate of up to 750 liters per hour at 25 psi, ensuring sufficient fuel supply for high performance engines.
Static pressure is adjustable from 25 psi to 80 psi, allowing precise adaptation to specific engine needs.
1:1 Fuel Pressure Rise Ratio: The regulator maintains a 1:1 pressure rise ratio, ensuring a proportional increase in fuel pressure based on boost pressure for supercharged engines.
Increased Durability and Reliability: Dual-layer diaphragms provide exceptional strength with a burst strength greater than 500 psi, ensuring long-lasting reliability under extreme pressure conditions.
The Teflon copolymer valve seat combined with a stainless steel ball valve helps maintain fuel pressure longer after shutdown, making it easier to restart the engine.
Durable Materials: Designed to be compatible with a variety of fuels (unleaded, ethanol, methanol, and diesel), the regulator is manufactured with materials that provide increased resistance to aggressive fuels.
Sealed Adjusting Screw Design: The spring preload adjusting screw is sealed with an O-ring, ensuring no vacuum or boost leaks even under pressure.
GFB FX fuel pressure regulators offer a unique blend of performance, durability, and flexibility. Whether you're a racing enthusiast looking to maximize your engine's performance or need a reliable regulator for your everyday vehicle, the GFB FX will meet your expectations with advanced technical solutions and high robustness.
