Female to Male Extender Fitting; Size -12AN

The Female to Male Extender Fitting -12AN from VIBRANT PERFORMANCE is a critical adapter for high-flow fuel, coolant, and hydraulic line routing in custom automotive builds. Whether you're extending AN hose runs to relocate fuel injection components, remote-mount filters, or intercooler systems, this fitting bridges the gap between direct connections and custom plumbing layouts. Engine bay real estate is precious, and sometimes your line terminations don't reach where you need them—that's where this extender delivers simplicity and reliability without requiring custom-bent hard lines.

This -12AN adapter features female inlet threads on one end and male outlet threads on the other, allowing seamless integration into existing AN hose systems with zero modifications to your donor lines. VIBRANT PERFORMANCE engineered this fitting for aluminum construction and precise JIC thread geometry, ensuring positive seals under boost and sustained fuel pressure without weeping or leakage. The compact 3.54-inch length makes it ideal for tight engine bays where even small extensions matter; at just 0.11 pounds, weight penalty is negligible in performance applications. AN -12 sizing (nominally 3/4-inch ID) handles high-volume fuel delivery for turbocharged and supercharged platforms without flow restriction.

Fabricators and tuners rely on this extender when upgrading fuel systems on LS swaps, Coyote engine conversions, and custom fuel rail relocations where factory routing won't accommodate aftermarket components. Use it to extend from fuel pump outlet to filter inlet, or from filter to regulator when clearance is tight. This adapter pairs with standard AN hose fittings (crimped or reusable), making it a drop-in solution for any shop stocking -12AN components. Critical for pressure systems—always verify hose and fitting compatibility, use appropriate crimp or fitting style for your hose, and test under pressure before full-power operation.
