Thanks to all and no apologies needed, DKontheroad has been sending me info via text and has been a GREAT help to me thus far. We were stumped as to why all of a sudden the air valve would go down to zero and the pumps couldnt move the air gauge until I started the engine and then the gauge would start to work.

After starting, the gauge pressurizes and begins to operate normally until the next time I found it at zero with pump running. it's like it needed a boost to get it going again or maybe the "unloader valve" has something to do with it. I dont seem to have any leaks in and or around the dryer valve and or fittings.
