Diesels have vacuum pumps too..


Make sure the switches are good on the v/c and might need to generally go over things. If you had a few broken vacuum actuators in doors or a/c they can contribute to low vacuum.

These cars are really reliable, just need to go through things one by one.

When you pull the line off the prefilter it should flow nicely. There is a tank screen which can become pluged-but I haven't seen it. Ussually a bad or clogged filter.
