    They go from the fuel pumps to the crankcase to operate the pumps with crankcase pulse.

    Which pulls the fuel from the gas tank to the carbs. Why did he say to replace them?

    Well Bill said they look ragged. There are 3 hoses ( I believe they are vacum lines.) then there are 4 parallel (connect all three carbs together.) Can I get these from auto parts or Yamaha store? I have a 99 XL 1200

    I really like the quality of the OEM lines.
