2nd air gauge not working

[stevesparts]

just got back..have to work sometimes :). but i found a very sneaky hole in a 1/2 inch line(by the air drier) and fixed the hole,but it did not fix it :( the gauge is responding better(more) but still diving to zero.sitting there for a bit then comes back still no buzzer or bells but its better. so will try to work on it some more this weekend.
