Propane is liquid in the tank, pretty much like the stuff you see in a cigarette lighter. I'll have to talk to the delivery guy. I've never actually watched him top off the tank. I'm sure you're right, though. |

I'm sure you're right, though. I have had several long talks to my gas supplier when I was considering converting my outboard to propane. There is a liquid pick up in most tanks but they are real guarded about telling you how to use it and they absolutely will not talk to you about a transfer pump in residential zoning. There are a couple of internet discussions telling you how to fill 20# tanks from your bulk tank. It is a lot easier with an above ground tank but mine is buried. Basically you cool the 20# tank and hook it to the liquid line of the bulk tank. It is not nearly as fast as the pump. === Any pump certified as safe for gasoline should be OK. Leak prevention at all of the fittings is the major issue other than grounding/spark avoidance. |
