OK, I got the hose. How about pressure regulation? Is the pressure from the larger tank a problem?

Thanks for all the help

The pressure from a big tank is the same as from a little tank—namely, the vapor pressure of the propane. (Technically speaking, that's only true so assuming the temperature of the propane is the same. A small tank will cool down more quickly as the propane vaporizes, and will thus have a little lower pressure as time goes on than the larger tank, but that's of no practical consequence here. It does matter when trying to run a large appliance from a small tank.)
