you shouldnt need to remove the pump. With a little patience and some good need nose pliers you can do it yourself. While your at it replace the other vac elbow which is easier to get to. Job will cost you $6 and your time.
After doing that get the codes cleared. The vac leaks can cause alot of different codes to pop up over a long period of time. Since you probably dont have the too unhook the neg battery cable over night. See what pops up if the CE light even comes on anymore.
