Shut Off Valve -8AN

The Vibrant Performance Shut Off Valve -8AN is a manual inline shut-off valve engineered for high-flow fuel and coolant systems in performance and racing applications. Featuring dual 8 AN male ports for seamless integration into -8 fuel lines or coolant circuits, this valve provides positive flow control with a single lever mechanism that enables quick system isolation during maintenance, troubleshooting, or emergency shutdown scenarios.

Constructed from lightweight aluminum and finished in black anodize, the valve resists corrosion while maintaining minimal weight penalty—critical for race-focused builds where every fraction of a pound impacts performance. The manual operation design eliminates dependency on solenoid activation or electrical systems, making it inherently reliable in stripped-down competition vehicles or as a redundancy backup in fuel system configurations. The compact footprint (3.8 × 1.55 × 5.4 inches) and 0.39 lb weight integrate cleanly into tight engine bays without requiring custom bracketry or rerouting of existing line runs.

This valve is purpose-built for fuel system isolation in drag racing, road racing, and high-performance street builds operating with -8 hose or hard-line plumbing. It serves equally well as a diagnostic isolation block or as a safety shutoff for systems requiring emergency liquid transfer termination. Buyers working with carbureted or EFI fuel delivery—or coolant bypass loops in modified engine packages—will find this valve's straightforward manual actuation and proven Vibrant Performance engineering to be dependable solutions for system control without complex electronic integration.
