I'm just placing the spider tank and attaching coolant hoses on my series 6 with a 912ULS that has the dynafocal engine mounts. The pictures in my manual are ambiguous about the placement of the spider tanks. One photo shows the 1" hose pointing rearward and above the rear engine mount tube and another shows it under the tube. The location will determine all the upper hose placement, bends needed, and hose lengths accordingly. I'm convinced its not really critical where the spider tank is exactly located but I don't want to stick it somewhere that will interfere with something else down the road in the assembly process. Does anyone have a top view photo of a similar engine / motor mount config that works and fits with all the other associated parts?
