Would anyone be so kind to tell me how I should route the fuel line on a '72 CB350F, how long should it be. Are there pictures or books available for the Kei Hin carbs? I've got the engine cleaned up and running good, but when I got this bike it had about three feet of fuel line from the tank to the carbs. Can someone tell me what the other two connectors next to the fuel input are for? Nothing was connected to these. There was also nothing connected to the over flows. Approximately how much fuel line would I need to purchase if replacing all lines?
