12AN Single Inlet - Dual 8AN ML Outlets Y Adapter

The 12AN Single Inlet - Dual 8AN ML Outlets Y Adapter by REDHORSE PERFORMANCE is a precision hydraulic distribution component designed for high-performance fuel, coolant, and vacuum line applications in modified and turbocharged vehicles. As a seasoned mechanic, you'll recognize this adapter as essential plumbing for complex engine builds where fuel systems, intercooler circuits, or boost control lines require controlled splitting from a single source into two separate destinations. This Y-adapter eliminates the need for custom fabrication or restrictive tee fittings, providing a factory-quality solution for symmetrical dual-outlet routing.

Constructed from billet aluminum with precision porting, the 12AN inlet accommodates larger flow volumes while the dual 8AN ML (male) outlets maintain balanced pressure distribution and minimize turbulence. REDHORSE's tight manufacturing tolerances ensure leak-free performance under boost and thermal cycling—critical in turbocharged, supercharged, and LSx swap applications where adapter failures can cost hours of troubleshooting. The compact footprint (4 x 1.5 x 6 inches) and lightweight construction (0.305 lbs) make installation feasible in tight engine bays without requiring extended hose runs or excessive bends that rob efficiency.

Street and strip builders, drag racers, and drift enthusiasts benefit most from this adapter when upgrading factory fuel systems to support larger injectors, twin turbo setups, or secondary boost-cut circuits. It integrates seamlessly into LS conversions, S chassis turbocharged builds, and modern engine platform swaps where OEM harnesses don't align with custom line layouts. Verify your hose end configurations (12AN and two 8AN fittings) before ordering, and confirm pressure ratings exceed your system's maximum PSI; REDHORSE adapters are engineered for boost applications but should never be undersized for your target fuel pressure or coolant temperature.
