Propane level
How much does the level of propane, in a tank, change with the change of ambient temperature? As the weather has warmed the level in our tank has gone down about 2 to 3% each week in the past couple o...

It's not a pressure gauge, it's a level gauge. In order for pressure to increase the liquid needs to vaporize, which heat will cause, more vapor less liquid, thus lower level.
I did turn the valve off firmly, still level went down, until this week.
I've had one in the past where the valve stem packing on that valve leaked.

Huh, No! As temperature rises the both the liguid state and vapor state expand in volume. Since it is a saturated liquid state in the tank the vapor pressure also rises. The end result is the liquid level will rise (it is non-compressable in this temperature range) and the vapor volume will actually decrease while pressure increases.
If your liquid level is going down with temperature increase it is absolutely a leak somewhere.
