Y-Fitting - 1 #12an Male & 2 #8an Male

The Y-Fitting – 1 #12AN Male & 2 #8AN Male by Magnafuel/Magnaflow Fuel Systems is an essential distribution component for high-performance fuel system builds, custom engine swaps, and complex fuel delivery architectures. This fitting serves as a single-inlet, dual-outlet manifold that consolidates fuel flow from one primary line into two secondary branches, making it ideal for applications requiring staged fueling, dual-carbureted setups, or parallel fuel pump configurations. Whether you're building a street performance engine or a dedicated competition fuel system, this adapter bridges incompatible AN line sizes with precision.

Manufactured to Magnafuel's exacting standards, this Y-fitting features a robust aluminum construction engineered to handle fuel system pressures up to typical high-volume pump specifications without leakage or degradation. The #12AN male inlet accepts a larger-diameter hose, allowing it to draw from a primary fuel source or pump output, while the dual #8AN male outlets enable flow distribution to smaller-bore secondary lines feeding carburetors, fuel rails, or distribution blocks. The precision machining and anodized finish resist corrosion in harsh underhood environments, and the male threads on all ports accept standard AN-rated hose ends or adapter fittings, ensuring compatibility across aftermarket fuel system components.

Mechanics and engine builders installing twin-carburetor conversions, multi-fuel-rail systems, or auxiliary fuel circuits rely on this fitting to maintain pressure balance and prevent flow restrictions. Its compact footprint (3.05 x 1.25 x 3.8 inches) fits tight engine bays typical of classic and modern hot rods, and the modest 0.24 lb weight keeps underhood mass minimal. Verify that your inlet fuel line carries #12AN-rated hose and both outlet lines are compatible with #8AN adapters before purchase; proper hose sizing ensures leak-free operation and consistent fuel delivery across your modified fuel system.
