Correct Hose Materials for 400i

Hi all, I am working on making my 400i correct and I am wondering if any of you could help me with a couple of items? What is the correct material (and the use for that matter) for the hoses that run into the exhaust pipes just behind the headers? (I am pretty certain that the green hydraulic hose on mine is not Ferrari factory correct.) Is there a good inexpensive source for the braided cloth covered vent hose and vacuum hoses? Also does anyone have a low cost source for a washer bottle/bag? All assistance and information is greatly appreciated.

 

Although I have an 85 308 many of the 1980's ferrari share the same hose materials and types. I sourced most of my new hoses including the ones that come off my exhaust/blow by system from Italian Car Parts. They cover your 400i. Also, add any pics you can of that green hose.
