I used 2 90deg aluminium bends and some 76mm silicone.
I actually have 600mm of silicone tubing left as I only used 400mm and bought a meter. Also I have a breather but it wont bolt straight on believe its 25mm diameter but will check if wanted. I think I may have some of the flexi Neoprene tubing thats also 76mm that I decided not to use.
