I'm one of those who use to pour jerry cans into mr Funnell, I now put jerry can on towel use ball siphon hose into Funnell but can won't fully empty until I hold it up when level is low, I have an spare electric pump and intend to try set it up with power from ride on mower, method of a drum and pump is fine but, filling the drum is a problem, service station require the drum to be on the ground, I don't know if they accept a wire grounding, when you get the drum to plane what do you do, can't refuel in hangar, do you keep drum outside or leave in trailer, I find the drum a little problematic. A dedicated fuel trailer would be fine but a little costly.
