Dual Feed Line Dual Feed Fuel Line Holley 4150/4500 is a fuel-delivery component for building or servicing the line between the fuel source and the engine. Proper fittings, feed lines and hose connections keep fuel delivery organized, sealed and routed away from heat or moving parts.
Match the listed fitting size, thread, hose diameter and carburetor/fuel-system style before installation. Fuel connections should always be checked carefully for leaks after assembly.
