Fuel Distribution Block Y-Block Female -8 AN

The Vibrant Performance Fuel Distribution Block Y-Block Female -8 AN (part number 10893) is a precision fuel line manifold designed for high-performance fuel system plumbing in custom and modified vehicles. This black anodized aluminum Y-block consolidates multiple fuel line connections into a single compact distribution point, eliminating the need for separate tee fittings and reducing clutter under the hood.

The block features one -8 AN female inlet port and dual -8 AN female outlet ports, plus an integrated 1/8-inch NPT female port for gauge, sensor, or pressure relief applications. The -8 AN configuration handles fuel flow rates typical of high-displacement engines and forced-induction setups, where oversized fuel lines reduce pressure drop and improve flow efficiency. Black anodized aluminum construction provides corrosion resistance and a finished appearance, while the compact 3.4 × 1.2 × 3.5-inch footprint fits tight engine bays. Weighing just 0.35 pounds, installation is straightforward with standard -8 AN hose fittings and adapters.

This Y-block is ideal for builders upgrading fuel systems on carbureted engines, EFI swaps, high-flow fuel rails, or dual-fuel configurations where branch distribution is essential. The manifold approach reduces connection points compared to traditional tee fittings, improving reliability and simplifying custom fuel line routing. The additional NPT port accommodates fuel pressure gauges, fuel pulse dampers, or proportional pressure relief valves common in performance fuel systems.

Vibrant Performance is recognized for precision-engineered fluid transfer components in motorsports and custom automotive applications. The -8 AN standard (1/2-inch hose) sits between -6 AN (practical for most street engines) and -10 AN (for extreme flow demands), making the -8 AN block the go-to choice for serious fuel system upgrades without over-engineering.
