I am interested in finding a replacement quad gauge if you are not looking to pick it up. I am having problems with my gauge too! After disconnecting it from the back of the gauge and reinstalling it My pressure came back up to 60 (had been reading in 80's). Not as high but it did come back. I noticed that the connector on the back of the gauge moves a little. The other ones do not. I have No confidence in that gauge! A direct gauge seems like it may be a great add on. Interested in your set up if have the time to do pics. Thanks
