Y-Block Fitting - 12an to 2 x -8an

The Aeromotive Y-Block Fitting - 12AN to 2 x -8AN (part number 15677) is a precision aluminum fuel distribution component engineered for high-performance fuel system applications. This Y-block fitting consolidates flow from a single 12 AN male inlet into dual 8 AN male outlets, making it ideal for fuel systems requiring split-line distribution to multiple fuel pumps, carburetors, or fuel rails. The black anodized finish provides corrosion resistance in harsh underhood environments while maintaining lightweight construction at just 0.23 lbs.

The 12 AN inlet-to-dual 8 AN outlet configuration preserves flow capacity across both output lines while reducing system complexity. Aeromotive's aluminum construction balances durability with weight savings—critical considerations in motorsports, marine, and high-performance automotive builds. The anodized finish resists oxidation and fuel permeation, extending service life in both carbureted and fuel-injected setups. This fitting is compatible with standard AN hose, fittings, and adapters, allowing seamless integration into existing fuel system architectures.

Builders and technicians rely on Y-block fittings for dual-pump fuel systems, motorsports applications, and aftermarket fuel distribution networks where pressure regulation and flow splitting are essential. Whether supporting carbureted engines with two mechanical pumps or modern EFI systems with redundant fuel circuits, this fitting handles the distribution task with proven Aeromotive reliability. The compact dimensions (3.65 x 1.3 x 4.9 inches) fit tight engine compartments without sacrificing functionality.
