Pump options for pentane.

[cyclopath]

this methanol pump might do the trick.

@cyclopath

Both pushed and pulled, including priming, through a filter. Almost emptied it too (pumping air). Cold didn’t phase it. Not as fast as N2 (and N2 does that other stuff).

Caveats: Came lubicated. Intended for fuel not food. Leave intake screen accessible or supplement it with something both bigger & smaller.

Materials and construction appear appropriate. I removed lubricant and cleaned everything thoroughly.

Want the ability to feed it 3-20V and reverse it. Should be fairly simple.
