Liquid Propane Leak

[pat123]

I was shooting my hybrid for the first time today. it worked a few times and then it messed up. I put the 20 psi in my meter then opened the meter and began pumping air in it to 30 psi. at about 20 psi I noticed that the psi leveled off then slowly fell. I thought it was leaking so I turned off the compressor. I had the meter closed and I noticed the pressure rising. liquid propane was coming through the hose attached to the propane tank. I unplugged the electric bbq lighter. then opened the union to let out the propane.

I thought that there was a leak causing the pressure to drop while I was pumping it up but after thinking about it I think that the coldness of the liquid propane made the air cold causing it to lower the pressure.

I think I shoud have had a valve between the propane tank and the compressor. I think the pressure of the air from the wrong side broke the valve on the propane tank.

any thoughts?
has anyone else had this problem?

Hmm interesting, my air and propane systems are separate so never had anything like that. Not exactly clear on your setup though.

it doesn't have the propane tank on it in this pic but it attaches at the gold hose adapter.
It also has a pressure gauge not shown in this picture.

Try keeping the propane tank upright and lower than the gun itself. I have this trouble (liquifying) sometimes with my advanced combustion doing a lot of level shooting or I operate the meter while the gun is aimed level or somewhat downward. If I keep it pointed even slightly up all the time I don't have any trouble with it.

My tank is permanently mounted parallel with the chamber.
