My question is, this hose does not have a hole in it for the "break booster check valve hose" which one branch has a connection to the accordion hose. I know this is an 01.5 issue I believe. Does the system just releases excess air into the accordion hose? and what should I do to get around it with the new accordion hose? just cap it off? or tap a hole?

Here is a picture taken from someone whose check valve failed, the check valve is circled but the plug that plugs into the accordion can be seen

THANKS!

tap it

Did you do this? or are you just recommending it? I'll most likely go that route.

Cap it off.

Take out the grommet from the old one, make a new hole the same size in the RS4 accordion. Be sure to check the position of the hole before you drill by test-fitting it.

drill it use the gromit from the stock accordian hose and install it . done

Could you explain why you recommend drilling over capping?
