I'm not familiar with the vacuum pump idea. I can't really help you out there. You may want to invest in a BMW oil filter wrench before hand. Just makes it easier. Also it is sometimes really hard to pull the filter out of the housing once out of the car. You just gotta yank on it till it comes off. Also people argue about which direction to install the new filter. I think the general consensus is to put it in with the lettering facing up.
