The Inline Shut Off Valve 8AN Male Inlet/Outlet by REDHORSE PERFORMANCE is an essential fuel system component for custom engine builds, turbo upgrades, and performance fuel injection setups. Whether you're running a high-horsepower street engine, a race car fuel system, or installing auxiliary fuel supply lines, this inline valve provides reliable flow control and isolation capabilities. Mechanics and fabricators rely on shut-off valves to safely isolate fuel delivery during maintenance, testing, and emergency situations without breaking fuel lines or draining entire systems.

This valve features 8AN male threads on both inlet and outlet ports, making it compatible with standard AN-style fuel line adapters, fittings, and hose assemblies widely used in performance automotive applications. The compact design—measuring just 3.8 x 1.4 x 4.7 inches and weighing only 0.23 pounds—allows for installation in tight engine bay spaces without compromising fuel system layout or plumbing aesthetics. REDHORSE PERFORMANCE engineering ensures dependable sealing under pressure, with the inline configuration allowing full fuel system isolation at a single point, eliminating the need for multiple shut-off locations or complex manifold modifications.

This valve is ideal for fuel system diagnostics, carb tuning sessions, fuel pump testing, and emergency fuel isolation on street cars, drag cars, and off-road vehicles. Custom fuel system builders and engine swap professionals benefit from the straightforward 8AN male inlet/outlet configuration, which integrates seamlessly with braided stainless steel hose, hard-line installations, and fuel rail assemblies. Installation requires no special tools—simply position the valve in your fuel line run and secure with standard AN fittings and a wrench, ensuring proper torque to prevent leaks under operating pressure.
