Difficult to make out your picture. I think a lot of people take a pipe from the oil filler up to a breather box or just straight to an air filter. I think it’s best to have a T piece for the oil fumes to go to both carbs to balance it out. As far as I know it to do with how powerful your set up is as to whether you need a breather box or not but I would say you should not have much oil going up the pipe unless there is a serious problem.I just have a small breather filter on the oil filler outlet with my newish dual carb 34 ICT set up.
