I'll try to be helpful, unlike some of these other clowns.

First, if you installed an OPD valve on the tank, that's wrong, you need a POL shutoff valve.  POL valves are still allowed on RV tanks, and you need a standard RV fill valve with the 80% valve that is part of the RV tank system. 

Did you install these?  http://www.anyrvparts.com/ProductDetail.asp?PID=11652&SID=29&DID=45

Subject: Propane tank

So I bought a bay window propane tank cheap and refurbished to new. All works as far as I can tell.

Here is my issue. I bought a heater buddy extension, like 10 feet, that has an acme valve in one side and a quick connect for my cook stove on the other. No matter what I do o can't get it to work. I have slightly turned, left, come back, turned more, etc.

I have tried turning quickly, slowly, very slowly, fast slow, connect one side, then the other, etc. Nothing works...Nothing!

I have confirmed the gas is in there and is clear and flowing when I push the plunger from the tank.

it seems to be my hoses. I have bought 2, one with regulator, one without, neither work.

So, not sure what else can be done, at the end of my whits. Any suggestions? Sure would be nice to ditch the 1 pounders.
