Intended for street and competition use where increased flow is required, the VRS-4150 Carburetor Fuel Line kit is designed specifically for the VRS-4150 and will not fit other 4150-style carburetors. This all-black kit features Russell Twist-Lok hose and -8 AN 6061 aluminum fittings. The 1/8” NPT inlet fitting houses a threaded bung for a fuel gauge. The kit is simple to install and connect to any VRS-4150 carburetor regardless of CFM size.
