81 300SD Pics of door lock pump repair
 

No, the pump still does not have vacuum but it works. I have pics showing how to take it apart, put everything back in the right order, and close it up. But with the Mityvac it will not hold vacuum and when I hook it up, it runs but produces no vacuum. I am stumped. Everything is tight and I cannot find out what is leaking.
