I ended up plumbing rubber tube pipe for the larger pipes to the throttle body.
The smaller pipe which has a one way valve on it and runs from the battery side rear rocker cover is the real pain to get to.
That breather outlet on the rear rocker cover is tiny and gets blocked easily and you cant get to it to clean it without pulling a heap of bits off.
I found the small one way valve was coming apart and sucking air.
Yet to find a part number for that.
