I am working on reconditioning an AAR for DJet, and would like to see if anyone can clarify, when the unit is in the fully warmed condition and closed, how much vacuum should be getting past? In other words, how do I know if the reconditioning effort worked? Should one side hold a vacuum?
I don't own any vacuum tools, but with the AAR hooked up in the car and after warm-up, you should pull the hose on the side/port going to the air intake and see if it is sucking air in or not. Of course, it should not.
Another more rudimentary test prior to install is to ground it, hook up 12 volts and wait a few minutes. The base of the pot should warm up and should not be able to suck air through the unit (this time trying to pull air from the other side/port).
