Does anyone know if it is possible to take the outside face plate of the vacuum pump off in order to reseal it and stop the leaks? I was unable to find any diagrams showing the inside of the vacuum pump. I might be able to get away with using some ultra black silicone on the outside of the vacuum pump and it actually stopping the leak however I would like to fix it right if possible.

There is a o-ring on the outside of the vacuum pump that can be replaced. There was someone with a breakdown of the vacuum pump a while back. Did you get all of your sensor problems resolved?
