Y-Block Fitting - 10an to 2 x -8an

The Aeromotive Y-Block Fitting - 10AN to 2 x -8AN (MPN 15675) is a precision aluminum hydraulic adapter designed for fuel system distribution and custom fluid line routing in performance vehicles and motorsports applications. This Y-block configuration allows a single 10 AN male inlet to feed two independent -8 AN male outlets, making it ideal for situations where fuel or coolant must be split into parallel circuits without pressure loss. The fitting serves as a critical junction point in high-flow fuel systems, turbocharger cooling loops, and transmission cooler installations where system redundancy or balanced distribution is required.

Constructed from lightweight aluminum and finished in black anodize, this Y-block fitting delivers corrosion resistance and durability in demanding underhood environments. The anodized surface protects against oxidation while maintaining a professional appearance on visible installations. Each outlet is sized identically at -8 AN, ensuring balanced flow distribution and eliminating pressure differentials that could cause cavitation or uneven circuit performance. The compact 3.65 x 1.25 x 4.9-inch footprint allows flexible packaging in engine bays and chassis where space is constrained, while the 0.19-pound weight contributes minimally to vehicle mass—a critical consideration in motorsports builds.

This fitting is essential for builders planning dual fuel pump configurations, parallel fuel injection staging, split cooling circuits, or any application requiring inlet-to-dual-outlet flow control. The 10 AN to -8 AN step-down ratio accommodates systems where source flow exceeds individual circuit demands. Technicians and fabricators benefit from the proven Aeromotive engineering and compatibility with industry-standard AN braided hose and crimped fittings. Proper installation requires appropriate AN hose sizing, thread sealant on male ports, and secure fixture to prevent vibration-induced loosening during high-rpm operation or transient pressure spikes.
