I have a 1986 Mallard I think i have a older 2 stage regulator the tank is built in when i have it on air seems to come out a small hole before the vent most of the time i can put my finger over the hole isit air or propane

If it is propane you will freeze your finger. Or at least it should be very cold. Did you notice that when they filled your tank they wore gloves?
Does it smell? Propane has a bad smell added to it so you can smell it if it leaks.
