OK, it isn't worth over thinking. There is no difference inside of a glow pump there there is in a gas pump. You just need to use gas proof line like Tygon or even some of the clear lines you find in hardware stores. In my case I'm using both types. It's just a cheap glow fuel pump and been with me for years on my gas can. That's it. Just the line. I can either get the kit to turn a cans lid into a gas or fuel can or make my own lid. When I buy stuff like alcohol I make sure the cans I buy have the big lids so I have room to convert them. You can do the same thing with just copper or brass tube and solder. When one can is getting low on gas I take the other can and mix up a new gallon. When needed I just trade the caps/lids. If I'm going to the field I can remove the fuel cap nd install the other lid so it doesn't spill if it tips over. Free cans, home made lid/cap and a cheap Magnum glow fuel pump. There is nothing in the pump that the gas will attack and eat. Gas and glow pumps can be used first on glow fuel then the cap can be installed in a gas can, pumped out a crank or two then used. The one pump can be used for both types of fuel without problems. It's the neoprene fuel line that gas will attack and eat.
