That's the hose I T'd in to for the VO system, but I pretty much replace that hose with a longer one that goes around the front of the filter canister instead of over it...you can kid of see it in the pic. Fishing the hose between the filter canister and the IP was a little tricky if I remember, but in the end its not kinked or squeezed anywhere. Makes oil changes a little easier...I still have a few vacuum lines to move out of the way when I'm taking the top off.
