Rebuild Kit for Shut Off Valve 6AN & 8AN Bodies

The Rebuild Kit for Shut Off Valve 6AN & 8AN Bodies from REDHORSE PERFORMANCE is an essential maintenance component for fuel system integrators and performance engine builders working with high-flow fuel control systems. Shut-off valves are critical safety and functionality devices in fuel delivery networks, particularly in racing, forced induction, and custom fuel cell installations where precise flow control and reliable fuel isolation are non-negotiable.

This rebuild kit addresses the wear and degradation that occurs in valve bodies subjected to thermal cycling, pressure fluctuations, and fuel chemical exposure over extended service intervals. REDHORSE rebuild kits contain OEM-specification internal components—seals, springs, plungers, and valve seats—engineered to restore shut-off valve bodies to factory performance standards without requiring complete valve replacement. By utilizing premium elastomers, these internal components resist fuel degradation and maintain consistent sealing pressures across the operating temperature range of modern fuel systems, ensuring leak-free operation and reliable actuation of fuel isolation functions.

Engine tuners, fabricators, and DIY enthusiasts performing routine maintenance on custom fuel systems will benefit from the cost efficiency of this rebuild kit. It supports both 6AN and 8AN SAE J518 port sizes, accommodating dual fuel line configurations common in twin-fuel systems and backup fuel supply architectures. This kit is a practical solution for anyone looking to maintain or restore the functionality of their fuel shut-off valves.
