10AN to 8AN Y-Block Single Inlet Dual Outlet

The 10AN to 8AN Y-Block Single Inlet Dual Outlet fitting is essential for custom fuel system builds and high-performance engine modifications where flow distribution is critical. This adapter serves as a junction point in your fuel or coolant lines, allowing a single larger-diameter inlet to split into two smaller outlets, making it ideal for turbo applications, nitrous systems, or dual-feed fuel rails. Mechanics and enthusiasts rely on this fitting type to balance flow rates across multiple circuits while maintaining system integrity under boost.

Constructed with precision-engineered porting, the 10AN to 8AN Y-Block Single Inlet Dual Outlet fitting reduces turbulence and ensures even distribution from a 10 AN inlet to dual 8 AN outlets, preventing pressure imbalances that can cause fuel starvation or uneven flow in dual-pump setups. The compact design—measuring 2.75 x 1.4 x 3.75 inches and weighing just 0.21 lbs—fits tight engine bays without sacrificing strength or flow capacity. Built from aluminum or stainless steel billet stock, this adapter handles the demands of forced-induction and carbureted racing engines while resisting corrosion and thermal stress.

Fabricators and tuners choose the 10AN to 8AN Y-Block Single Inlet Dual Outlet fitting for mid-mount fuel cell plumbing, water cooling circuits on LS swaps, and boost-referenced fuel pressure distribution in carbureted nitrous systems. Its lightweight footprint makes it perfect for weight-conscious builds, while the standard AN hose thread pattern ensures compatibility with quality stainless braided fuel line and quick-disconnects. Installation is straightforward with a wrench—simply secure the inlet and thread both outlets into your distribution lines, then torque fittings to specification and verify no leaks under full boost or max RPM.
