6AN 302 Series PTFE Hose 3ft Black

The 6AN 302 Series PTFE Hose 3ft Black from REDHORSE PERFORMANCE is engineered for high-pressure fuel and fluid transfer in performance automotive applications. Whether you're building a custom fuel system for a modified engine, upgrading your cooling loop, or installing a precision transmission cooler line, this hose delivers the reliability that serious mechanics and enthusiasts demand. PTFE (polytetrafluoroethylene) core construction resists degradation from ethanol blends, methanol, and extreme temperature swings—critical when you're pushing fuel pressure limits or running aggressive ignition timing.

The 6AN size indicates a nominal 3/8-inch inner diameter, sized perfectly for carbureted and fuel-injected systems where consistent flow and minimal pressure drop matter. REDHORSE's 302 Series combines a smooth PTFE inner tube with a woven reinforcement layer and durable elastomer cover, meeting SAE J30R7 standards for burst strength and abrasion resistance. The black cover resists UV degradation and provides clean underhood aesthetics while the 3-foot length accommodates engine bay layouts from compact builds to large-displacement swaps. Hose ends accept standard 6AN fittings (aluminum, steel, or stainless) with no special adapter requirements, making integration into existing or new fuel systems straightforward.

This hose is ideal for builders transitioning from rubber hose to permanently routed applications, high-heat engine compartments, and systems requiring spill-free quick-disconnect upgrades. Mechanics working on turbocharged, supercharged, or naturally aspirated builds will appreciate the broad compatibility and lack of fuel compatibility issues when ethanol or methanol is in use. Installation is quick—measure your run, order fittings separately if needed, and secure with clamps or P-clamps in areas exposed to vibration. The 0.41 lb weight adds negligible mass, keeping total fuel system weight minimal on weight-sensitive builds.
