Carb Adapter Fitting 8an to 7/8-20 (Long)

The Carb Adapter Fitting 8AN to 7/8-20 (Long) is an essential component for fuel system modifications on high-performance and modified vehicles. This adapter bridges the gap between modern AN (Army-Navy) hose fittings and traditional 7/8-20 carburetor ports, making it ideal for engine swaps, fuel injection retrofits, and vintage vehicle restorations. Whether you're upgrading a classic hot rod with contemporary fuel delivery or adapting modern fuel systems to older carburetors, this long-format adapter provides the precise connection geometry your fuel system demands.

Engineered with precision threads and durable construction, the 8AN to 7/8-20 long adapter maintains reliable pressure sealing across varying fuel pressures common in carbureted and EFI applications. The extended length design accommodates tight engine bay layouts and angled mounting positions without requiring additional elbows or adapters, reducing potential leak points and simplifying plumbing runs. The 8AN side accepts standard braided stainless steel fuel line or AN hose, while the 7/8-20 end threads directly into original carburetor inlets, offering a clean mechanical interface that prevents fuel weeping at critical junctions.

This adapter is indispensable for engine builders, vintage restoration enthusiasts, and performance mechanics tackling carburetor-to-fuel-injection conversions or engine transplants. The long format proves especially valuable when routing fuel lines through crowded engine compartments where space is at a premium and clean, direct pathways are critical. Ensure proper AN hose sizing on the inlet side and confirm carburetor port thread compatibility before installation to guarantee leak-free operation under all operating conditions.
