  • According to my ancient parts book, it's called

    Hose, Preheat (gasoline units)
    Part number 503-1351

    An alternate part # is 503-1533-03

  • Great thanks for the help. I kind of thought that might be it but the parts explosion doesn't have a very good pic and was just confusing me which isn't hard to do. Once again thanks for the help
