⚙️ Application & Setup

The GFB 5752 provides a 1/8″ NPT female outlet, which can be configured in multiple ways:

• Fit a male-to-male coupler (e.g. GFB 5739) to connect directly to an FX-S regulator
• Add a hose barb fitting (e.g. GFB 5740) to run a remote-mounted fuel pressure regulator
• Use for fuel pressure sensors or gauges

✔ This makes it extremely versatile for custom fuel system setups and regulator relocation

⚙️ Product Overview

Modern fuel systems often lack convenient connection points for aftermarket regulators. The 5752 adaptor solves this by creating a dedicated threaded port straight off the fuel rail, allowing:

• Cleaner plumbing
• Easier regulator installation
• Flexible mounting options
