Call around and see if there are any specialty hose shops in the area.
I had a similar problem with a turbo on my DD, could not find the banjo bolt or water fitting to save my life. Went down to the hose shop and they made me a water line and sold me the banjo fitting. all for under $50
They are Mesa Hose in Costa Mesa CA, I don't think they have a website but if you still can't find anything give them a call (949) 645-2661
Good Luck
