plumbing up heater on a mk1 g60 conversion

hi does any one know which pipe off the g60 engine goes to the pipe that comes through the bulk head with the heater valve on it is it the rubber one that comes off the side of the head or is it the metal one

dont know for definate mate, but would imagine its the same for the DX and KR engines - the one from the head goes to the pipe with the heater control, and the one without the heater control goes to the metal pipe? - a supply and return :dontknow:

yeah it's the metal one
