DeatschWerks has expanded its carbureted fuel system lineup with PTFE dual feed fuel line kits and fittings designed to simplify installation and improve reliability. Unlike traditional rubber fuel lines, PTFE construction provides full ethanol compatibility while resisting fuel permeation, cracking, and degradation.
Available for 4150 and 4160-style carburetors, the kits feature pre-assembled PTFE hoses, hard-anodized components, and serviceable AN connections. Front and rear 1/8" NPT ports also provide convenient connection points for gauges, sensors, or nitrous feeds.
