The door vacuum pump reserviour which holds vacuum for the door locks, the check valve can leak and pull oil into the lines from the main vacuum pump.

2. The shutoff valve. the interior of the IP is bathed in oil. So if the diphram leaks oil it will get into the shut of lines.

3. The transmission line. The transmission modulator could leak and allow transmission fluid into the system. This one I have not done, but it is a potential fluid leak area.

Re: #1, So it's just enough to place a filter on one of the lines coming off of the main line and not both lines that come off of the main line?
