Upgrade to 100lb propane tank in Gas Forges Posted January 29 So I had something kind of odd just happen... Hopefully someone can explain this to me. I live in Canada which believe is relevant for this cicircumstance. I currently use a 20lb propane tank that you would for a BBQ that is filled by weight, I want to upgrade to a 100lb tank that is filled by pump, like you would fill up at a gas station for a propane powered car. The main reason is cost, the liquid propane pump is WAY cheaper than propane paid for by weight. So I made some calls to local gas fitting companies to find out what to do, where to go, what regulators I need, stems, valves etc. I was finally pointed in the right direction but when I asked about the valve for pump filling the guy put me on hold, came back on the line and flatly told me they don't do that and they can't get me what I'm looking for. His whole demeanor changed, it was really weird! What the heck did I say? Does anyone have any insight for a noob? Thanks.
