Hi, I recently discovered that my fuel mixing tube (038 130 085) is damaged and have had to order a new one from Germany as there's no Australian stock of this part. While I await it's arrival, I'm trying to confirm the procedure for fitment and have not found any detail as yet. It's entirely possible that it's simply a matter of sliding it into the fuel supply gallery in the head, but I want to be sure if there's any critical alignment requirement as the tube can be rotated from the Tandem pump end once installed. Any advice much appreciated.
