Russell Performance Fuel Hose Fitting

Russell Performance Fuel Hose Fittings: Precision for Every Fuel System

When it comes to building or rebuilding a high-performance fuel system, the fittings you choose are just as important as the hose itself. Russell Performance has built a decades-long reputation among professional racers, engine builders, and serious enthusiasts for manufacturing fuel system components that combine aircraft-quality materials with exacting tolerances. Their fuel hose fittings are a natural extension of that legacy — engineered to create secure, leak-free connections in demanding environments where fuel pressure, heat, and vibration are constant concerns.

Why Russell Performance Stands Out in Fuel Hose Fittings

Russell Performance fittings are built to the AN (Army-Navy) standard, a specification originally developed for military and aerospace applications. This means threads, seat angles, and dimensional tolerances are held to rigorous benchmarks, ensuring compatibility with other AN-spec components from reputable manufacturers. Whether you're plumbing a carbureted muscle car, a fuel-injected street rod, or a dedicated track build, the precision machining behind Russell fittings provides confidence that connections won't weep, loosen, or fail under pressure.

Materials matter in fuel system plumbing, and Russell Performance consistently chooses high-grade aluminum alloys for their fittings. Aluminum offers an excellent strength-to-weight ratio, natural resistance to corrosion from gasoline and ethanol-blended fuels, and the ability to be anodized for both protection and aesthetics. Russell's signature anodized finish — often seen in their iconic red and blue color coding for supply and return lines — makes line identification fast and intuitive during installation and maintenance.

What to Know Before You Buy

Fuel hose fittings come in a variety of configurations — straight, 45-degree, 90-degree, and 180-degree (also called "banjo" or "U-turn" styles) — to accommodate virtually any routing challenge in an engine bay. Russell Performance offers fittings in multiple AN sizes (commonly -4AN, -6AN, -8AN, and -10AN) to match different flow requirements. Choosing the correct size is critical: too small an AN size restricts fuel flow to the engine, while mismatched threads can cause dangerous leaks.

Russell fittings are also designed with assembly in mind. Their hose ends are engineered to work seamlessly with Russell Performance braided stainless and PTFE-lined fuel hoses, reducing the guesswork of mixing brands and ensuring the entire fuel line assembly performs as a matched system. For builders looking to maintain a consistent, professional-grade fuel system from end to end, pairing Russell fittings with Russell hose is a straightforward path to reliability.

Trusted by Racers, Built for the Street

Russell Performance's roots in motorsport mean their fuel hose fittings are validated in conditions far more extreme than everyday street driving. That racing pedigree translates directly to durability on the road. Whether you're replacing a worn factory fitting, upgrading to AN-style plumbing for better flow, or building a complete custom fuel system from scratch, Russell Performance fittings deliver the quality and peace of mind that serious builders demand.
