Thank you for the info. Did you also have to replace your valve cover to stop oil from getting into the hose?

I replaced the valve cover first and then replaced the vacuum pump 2 weeks later.
The new valve cover already got some oil in that time frame so the shop extracted every bit of it for me.
Be very careful when replacing the hoses. The nipples can be fragile if the valve cover is old. Someone suggested cutting the old hose in half with a razor blade but I didn't have to do that because my valve cover was brand new.
