Y-Fitting - 3 #4 Male

The Y-Fitting - 3 #4 Male from MAGNAFUEL/MAGNAFLOW Fuel Systems is a precision aluminum fuel distribution block engineered for high-performance fuel system applications. This #4 AN inlet y-fitting features one 4 AN male inlet port and dual 4 AN male outlet ports, making it ideal for systems requiring fuel line splitting or distribution across multiple downstream components. The purple anodized finish provides corrosion resistance while maintaining visual identification in complex fuel system layouts.

Constructed from aluminum with anodized surface treatment, this y-block fitting delivers durability in demanding fuel system environments. The #4 AN thread standard is a common specification in performance fuel systems, offering reliable flow capacity for fuel injection and nitrous oxide applications. The compact dimensions (3 x 0.5 x 3.75 inches) and minimal weight (0.04 lbs) ensure straightforward installation in engine bays where space and system weight are critical factors. The male inlet and dual male outlet configuration allows for flexible fuel line routing using compatible female AN fittings.

This y-fitting serves builders and technicians working on fuel-injected performance engines, custom fuel distribution systems, and multi-outlet fuel system layouts. It is suited for applications requiring fuel line splitting without additional manifold components, reducing installation complexity. The purple anodized finish aids in fuel system identification during assembly and maintenance, supporting organized build documentation and future service.

AN fitting systems are industry-standard in performance automotive and racing applications. The #4 AN size occupies a middle range between smaller #3 and larger #6 specifications, balancing flow capacity with system packaging constraints. Anodized aluminum fittings are chosen for weight savings and corrosion resistance, particularly in high-vibration and temperature-cycling environments typical of engine compartments.
