GFB 8156 Adjustable Fuel Pressure Regulator

The GFB Go Fast Bits 8156 is a high-performance adjustable fuel pressure regulator engineered to deliver precise, consistent fuel pressure for modified and high-output engines. Designed and manufactured by Go Fast Bits — a globally respected Australian performance parts brand — this regulator allows tuners and enthusiasts to dial in the exact fuel pressure required to support upgraded injectors, high-flow fuel pumps, and forced induction applications.

Maintaining accurate and stable fuel pressure is critical to engine reliability and tuning accuracy. The GFB 8156 features a robust, compact construction with a high-quality internal diaphragm designed to respond accurately to manifold vacuum and boost pressure, ensuring the correct air-to-fuel ratio is maintained across the entire RPM range.

Key Features:

• Adjustable fuel pressure output for precise tuning flexibility
• Compatible with both return-style and returnless fuel system configurations
• High-quality internal diaphragm for accurate, responsive pressure regulation
• Vacuum/boost referenced design to maintain consistent fuel pressure under all load conditions
• Durable billet construction for long-term reliability in high-performance applications
• Compatible with gasoline, E85, and other common fuel types
• Compact design for easy installation in tight engine bays

The GFB 8156 fuel pressure regulator is an essential upgrade for any serious performance build where stock fuel system components are no longer adequate. Whether supporting a forced induction setup or a naturally aspirated high-revving engine, this regulator provides the tuning precision needed to maximize power output safely and reliably.
