Hi guys,
I have bought these red hoses (värmeslang) for the heating system of my 915 sugga with an ED motor a few months ago at motoroldies.de but when I checked today I did not find them any more. Maybe they have been gone out of stock.
Please see the attached photos where they are used in my car. These are original from 1957 but still working. The new ones I am going to put on when I do some restoration this year.
Is that any help for you?
