I recently bought a house that has a 65 gallon LPG tank for the stove &
outdoor grill. I'm trying to determine how full it is. It has a pressure
guage that shows about 18 PSI at the moment. Given that the guage goes up
to around 100 psi, I'm guessing this ain't toooo full. Am I right, or can
you tell from the pressure reading?

TIA
