GFB 8070 FX-D Fuel Pressure Regulator (-8AN Ports)

🔧 Product Description

The GFB 8070 FX-D Fuel Pressure Regulator (-8AN Ports) from Go Fast Bits is a high-performance EFI regulator engineered for maximum flow, precise control, and OEM-like reliability.

Designed to handle everything from street builds to high-horsepower race setups, the FX-D features a 1:1 rising rate, multiple port configurations, and advanced sealing technology—making it one of the most versatile regulators on the market.

⚙️ Key Features

• 2x -8AN inlet ports
• 1x -8AN return port
• 2x 1/8” NPT gauge/sensor ports
• 1:1 fuel pressure rise rate (boost-referenced)
• Adjustable base pressure: 28psi – 72psi
• Double-layer reinforced diaphragms (burst strength >1000psi)
• Teflon co-polymer valve seat with stainless valve
• Fully serviceable design
• Multiple port options for flexible installation

🏁 Performance Benefits

• 🔒 Holds fuel pressure after shutdown (unlike metal-to-metal regulators)
• 🚀 Provides stable fuel delivery under boost
• ⚡ Improves startup reliability
• 🛠 Supports high-flow fuel systems (single to triple pump setups)
• ⛽ Compatible with multiple fuel types

🔬 Advanced Engineering – What Sets It Apart

Unlike typical aftermarket regulators that use metal-to-metal sealing, the FX-D uses a replaceable co-polymer valve seat:

• Creates a positive seal after engine shutdown
• Prevents fuel pressure bleed-off
• Ensures faster, more reliable engine starts
• Offers superior resistance to aggressive fuels

👉 This gives you OEM-like behaviour with race-level performance.

⛽ Fuel Compatibility

The FX-D is designed to handle a wide range of fuels:

• Pump petrol / gasoline
• E85 / Ethanol
• Methanol
• Diesel

Perfect for both street performance builds and motorsport applications.
