GFB FX-S 8051: The Ultimate Fuel Pressure Regulator Upgrade

Fuel Delivery… Delivered! 🚀

When upgrading your fuel system, ensuring proper fuel pressure regulation is crucial—especially with high-performance setups running larger pumps or E85. The GFB FX-S 8051 is designed to replace the factory Bosch clip-in regulator, providing superior flow capacity and adjustability to meet the demands of high-performance engines.

Why Choose the GFB FX-S 8051?

🔧 Direct-Fit Replacement – Clips directly into the factory fuel rail, eliminating the need for adaptors or extensive modifications.
💨 More Than 2x the Flow – Handles increased pump capacity without requiring a new fuel rail.
⚡ Adjustable Fuel Pressure (1.4 - 5 BAR / 20 - 72 PSI) – Unlike stock Bosch regulators, the FX-S 8051 allows precise tuning for optimal performance.
💎 Durability & Compatibility – Works with gasoline, ethanol (E85), and methanol.
🛠 High-Strength Components – Features double-layer reinforced diaphragms with a 500+ PSI burst strength and a Teflon co-polymer seat for better sealing and fuel pressure retention after shutdown.
📈 1/8" NPT Gauge Port – Easily install a fuel pressure gauge or sensor for real-time monitoring.

Upgrade Without the Hassle

Increasing fuel pump capacity is essential for high-horsepower builds, but the factory Bosch regulators struggle to keep up—often leading to excessive fuel pressure at idle. The FX-S 8051 allows you to run a larger fuel pump while maintaining proper pressure control, even with a stock fuel rail.

Unlike fixed-pressure Bosch regulators, the FX-S 8051 is fully adjustable, giving you the flexibility to dial in the perfect fuel pressure for your setup.

Fitment Information

📌 The FX-S 8051 is a direct replacement for many vehicles using Bosch clip-in regulators.
📌 It is taller than the factory regulator, so check clearance space before purchasing.
