Fuel Shut Off -6 Waterman Style

The Fuel Shut Off -6 Waterman Style is a critical safety and performance component designed for high-performance and competition vehicles where fuel system isolation is essential. Whether you're building a track car, preparing for emergency fuel cutoff in a motorsport application, or upgrading a modified fuel system, this inline fuel valve delivers reliable flow control in a compact, lightweight package. Weighing just 0.21 lbs, it integrates seamlessly into existing fuel lines without adding unnecessary mass to your vehicle.

Engineered in the Waterman style configuration, this -6 AN fitting fuel shut off features precision-machined construction that ensures smooth, reliable operation under pressure and vibration. The -6 AN port size (3/8-inch ID equivalent) accommodates moderate to high fuel flow rates common in fuel-injected performance builds, turbocharged engines, and fuel cell installations. Compact dimensions of 3 x 1.75 x 4.1 inches allow installation in tight engine bays or fuel cell compartments without requiring extensive plumbing rework, making it ideal for retrofitting existing fuel systems or new custom builds.

Competition drivers, fabricators, and serious enthusiasts benefit most from this fuel shut off valve, particularly in racing applications where fuel cell isolation is mandatory for safety compliance. Installation is straightforward—position it inline between your fuel pump and regulator or fuel rail, using standard -6 AN hose and fittings compatible with your existing fuel system architecture. This component pairs well with fuel surge tanks, aftermarket fuel systems, and custom fuel cell setups where manual or remote fuel cutoff capability enhances both safety and engine management control.
