Well I left early today and didnt get the info about the vac hose off /on, but i did check pressure. it was a lil over 36 with key switched on. with it running it was like 39/40ish range. Is that to high? Link to comment Share on other sites More sharing options...

deziped Posted October 6, 2007 Share Posted October 6, 2007 Your PSI is in the ballpark, and should be sufficient. Link to comment Share on other sites More sharing options...
