Male -8AN to Male 3/8in NPT 90 Degree Fitting

The Male -8AN to Male 3/8in NPT 90 Degree Fitting from VIBRANT PERFORMANCE is a precision hydraulic adapter engineered for custom fuel, oil, coolant, and boost system plumbing in high-performance engine builds. This 90-degree elbow connector bridges AN (Army-Navy) and NPT (National Pipe Thread) standards, making it essential for builders integrating modern fuel injection systems, turbocharger feeds, or remote oil filtration into older platforms or custom fabrications. Whether you're routing fuel lines around engine bay obstacles or adapting aftermarket fuel pressure regulators and gauges to legacy engines, this fitting ensures leak-free connections under pressure.

Constructed from durable aluminum, this adapter features a 90-degree bend that reduces hose runs and minimizes turbulence in fuel and coolant circuits—critical for maintaining system integrity during high-boost or sustained track use. The -8AN male end accepts standard braided stainless steel hose fittings (5/8-inch hose), while the 3/8-inch NPT male end threads directly into manifolds, filters, or sensor ports without requiring additional adapters. The compact design (3.54 x 1 x 6.3 inches, weighing just 0.11 lbs) allows installation in tight engine bays where space is at a premium, and the 90-degree geometry is superior to combining straight fittings and elbows, which introduces additional leak points and complexity.

Performance mechanics and engine builders rely on this fitting when retrofitting EFI systems into carbureted platforms, integrating turbo or supercharger fuel distribution blocks, or plumbing remote fuel filtration and surge tanks. It's indispensable for anyone upgrading fuel pressure regulators, boost-referenced fuel systems, or oil coolers on custom builds where NPT-threaded ports are the only available connection point. Proper installation requires thread sealant on the NPT end to ensure a dry connection under pressure; verify your system's working pressure rating and ensure hose clamps are properly torqued on the AN end for maximum reliability during acceleration and cornering.
