It was that pic, from stixvrad, that inspired me to do similar setup.

finally i have fitted the breather bypass today,and im very happy that the rubbish is not going into my intake

1/4 fuel hose and a 6mm brass T fitting

Just a Question for the mechanics on here if you look at the T piece, i have the hose running between the pushrod tubes how much heat would be there and will the fuel hose melt ?

This is the best option in my humble opinion. Its my understanding that the breather system needs the draw from the sucking in the air cleaner along with the piston strokes for the head breathers to work correctly in the first place. That said I run both my 2010 Street Glide and my 2018 Slim full of oil and I never see blow by to speak of in either air cleaner when I clean them? My engines are stock however with the exception of exhaust and tuner. I run some Techron in my gas about twice per season for good measure. Just my .02

As you can see, all that there is in that bottle is evaporated froth. No oil because I keep it on the low end of the stick.

Is the T fitting exeting through the back of your air box?
Very nice

Yes.
I originally had 2 hoses going through the back with no T and both hoses going to the ground. I got tired of leaving oil spots (my dad would call me and tell me my bike was leaking oil after being at his house) so I updated it to this "new design" with the catch can. Works well - no more oil spots on the ground.

On another subject (don't follow me :-)) going to hit 10K trouble free miles on the way home today on a stage III. Thank God no sumping nor transfer.

How much Heat can the fuel hose take near the pushrod tubes? i will ride it this weekend and keep my eye on the fuel line hose for melting.

not sure it really matters..but initial thought was not liking the breathers venting 'uphill'...just my perception anyway which could be wrong
