RHS Coolant pipe too small

[ftaffy]

Hi All,
Was replacing a leaking coolant line on my 2008 997.2 PDK C2S with a new pipe 997.106.624.03 - from Porsche and checked on the diagrams.
Went to install it and found that it was a smaller diameter then the previous pipe. :?:
Current does not have a part number i can see.

Has anyone else seen this? Was there a change in the coolant system piping?

The answer was right in front of me if i had held up the hose in the car and actually looked... i had the upper hose (return) which is a small diameter and slightly longer then the lower hose i need to replace.
