Ever notice when refurbishing your legendary H1/H2/S1/S2/S3/KH400 bike Kawasaki that correct fitting and looking fuel line is about impossible to locate? problem solved right here with my fresh in-stock METRIC black Mylar fuel line, correct for all Kawasaki triples. NOTE: you MUST tell me when making purchase the MODEL OF YOUR BIKE so i send you the correct line as S & H series triples take different sized line than the Z series bikes. this is 4mm ID and 9mm OD which is exact in appearance and fit for these bikes. It fits the petcock and carb fittings precisely, will NOT leak and stays soft and pliable for many, many years. Stop messing around with that crappy local hardware store or auto parts junk that never fits or looks right, and do it right the first time. YOU ARE BUYING 30 INCHES OF LINE HERE, enough to do your S-series/H-series or S series triple bike.
