I bought one of those Flame King
100 lb., 29.3 gallon propane tanks from Amazon.31h+m3cx3oL._AC_SY400_.jpg
I installed it under the bus, bought a POL to Type 1 adapter
It doesn't fit my propane tank. Is it a bad adapter, or does this particular propane tank have a different kind of connection than I thought? There is no documentation on the Amazon page, the manufacturer's page, or with the propane tank itself.
