Well I don't normally spout off, so bear with me.
Last year I had my propane tanks filled in NC. Since then I have had problems with one tank, I could never get any flow out it.
The over fill safety was so full, it shut all flow down. According to the valve information, this could never happen, as the valve should have shut all flow down before the tank reachs more than 80%.
Using the bleed valve in wide open space, I drained off the tank. Liquid propane came out for the first few minutes, than vapour. When vapour started, I closed off the valve, and reinstalled the tank in the camper. The tank now works fine.
Should I be changing out this tank? or was it just over filled by force.

Sounds to me like the last one who filled your tank didn't open the over flow valve. I would make sure to watch carefully on the next fill and see if it still gives you problems.

I agree with Mooney. If I have my tanks filled by someone new, I always watch to insure they open the overflow valve.

I just had a problem my dealer is blaming on a tank overfill. My automatic water heater gas valve failed and during the changeout, I found it was dripping oil. When I asked my dealer about it, I was told oil in a propane line is a direct result of a tank overfill and they suggested I check the main regulator as well.................guess what? More oil! Ended up replacing the main regulator and both cylinder lines as well.
Fortunately, the tanks were almost empty and after refilling to the proper capacity, I haven't had an issue. I'm hoping the appliances aren't too gummed up and that clean propane will help purge the lines I can't get to.

Not sure if it makes a difference but what was the outside temp when the tank was filled? Might have been cool/cold and gas expanded when warmed up. ?????

Stim;
If you're asking me, both tanks were filled last month in 80F+ weather. Not sure if it was one or both as they were done at the same time, by the same attendant............next time I watch more closely as I'm out almost $300.

There's been threads on this before. Thanks to 3+tons, we now know what this stuff is. It's not oil, it the caustic solution used to remove sulfur compounds from the propane. Yes, it's straw colored, slippery and viscous like oil, but it's not oil. It's highly caustic and will eat up regulator diaphragms, hoses and controls.

you should be able to use a small flat head screwdriver, loosen the bleed screw slightly, allow contents to purge untill all white gas stops, it should expell almost a clear gas. when that is clear, you tanks will have the proper level of lp gas in them. that also leaves room for expansion with temp changes.

This is what I did. But I was told the over fill valve would limit the fill, so you should never have to bleed off the liquid gas. I guess this works only in theory.
It also stinks, in more ways the one, I know for safety reasons.
I guess by the responses, it also has happened to others.
