Just bought some replacement coolant hoses for an '00 C4. 996.106.250.55 supersedes to 996.106.850.05. But the hoses have a different contour at the coolant tank connection. The new hose has an S bend and is longer. Maybe made for a newer or different coolant tank? The nipple for the AOS hose connection will be further away if using the new hose, and not sure the AOS hose will reach? Is there another hose p/n that I should be trying to use? Thanks,
