Hi Andy
I have seen this a few times at the Nano meets but it as not been holes as yours is, the hose rubs on the engine cover and on a bolt the opposite side, you will to get another hose from a donna car or scrap car, once you have fitted the new hose put some conduit over the hose where it rubs.

The power steering can also rub on the compressor pulley, so also wise to tie that back when you can if you have not done so already.
