Jet Adapter Fitting - #3 x 1/8in x 1/8in w/Pill

The Jet Adapter Fitting #3 x 1/8in x 1/8in with Pill from Magnafuel/Magnaflow Fuel Systems is a precision-engineered fuel distribution component designed for high-performance fuel system assembly and modification. This Y-block adapter consolidates fuel flow routing in confined engine bay spaces, making it essential for custom fuel injection tuning, carbureted engine conversions, and racing fuel system builds where multiple fuel lines must interface at a single junction point.

Constructed from aluminum in a polished finish, this fitting features a 1/8-inch NPT female inlet and dual 3 AN male x 1/8-inch NPT male outlets, accommodating mixed line diameters in a single compact assembly. The integrated pill design maintains internal pressure consistency across outlet ports, critical for fuel delivery stability at high flow rates. The polished aluminum construction resists corrosion and integrates seamlessly with modern fuel system aesthetics. Compact dimensions (3.05 x 0.55 x 3.8 inches) and minimal weight (0.06 lbs) allow flexible mounting in tight spaces without adding dead weight to fuel delivery circuits.

This adapter serves fuel system technicians, engine builders, and performance shops executing custom fuel injection retrofits, multiple carburetor setups, or high-flow fuel system upgrades. The dual outlet configuration with mixed port sizes accommodates non-standard fuel line combinations common in engine swaps and vintage-to-modern fuel system integrations. Builders working on drag racing platforms, street rod fuel systems, and forced-induction engine conversions rely on precision fittings like this to eliminate pressure drops and ensure consistent metering across fuel distribution networks.

Magnafuel fittings are widely specified in professional fuel system assemblies because they maintain dimensional accuracy, resist fuel chemistry degradation, and deliver repeatable performance across engine operating ranges. This Y-block jet adapter is a core component for anyone standardizing fuel distribution architecture in a custom or rebuilt fuel delivery system.
