Yes mate I binned the lot, I connected the pipe to the original elbow then straight to the tank (as per Pat's instructions over on uk-mkivs) 
kool kool i thought so, just wanted to make sure! I'v got a catch tank sitting at home that i am going to put on till mine and barrys saikoimichi ones come. Its the type that you put a little oil breather filter on the top, dont know what affect that has?
