Does anyone know how the chain oiler is supposed to be connected on
the 73 and 74 Z1s. When I got the bike the chail oil pump and tank
were both there, but the hoses connecting them were not. My problem is
there seems to be a place for 2 hoses to connect to the tank and
only 1 place on the pump. I thought maybe the connection on the top
was just a vent or something but then I saw a picture on ebay of the
pump and tank not installed on the bike, in the pic there were 2
hoses and they were both connected to both the pump and the tank, so
then I figured the top port on the tank must be a return or
something. But I can't find any place to hook that second line
anywhere near the pump.
