Default Valley Coolant Hose and parts

Well, my 10 YO cat has become a little incontinent and dropped its cooling fluid.
It seems to be be dripping from the back and an inspection seems to suggest that it is the hose under the supercharger.
I have recently had a puffy radiator hose and the expansion tank replaced.
I plan on pulling the SC etc off and seen many links on this but no list of parts.
As I understand it from some of the links, the parts required are:
  • Heater Feed Hose
  • Return Hose
  • EGR gasket?
  • TB gasket
  • TB Elbow gasket
  • SC outlet duct gasket
Appreciate any help as I am not easily able to find the items I think I need on the parts diagrams.

Some of the hoses & gaskets such as the valley pipe will be as per the STR. Some posts give parts in the S-Type forum e.g. by Bull27 and tbird6

Proper name may be Throttle Body Coolant Return Hose
for google/etc searches.
