i don't remember name. they are cheap like 3 to 15 bucks.
clear pipe up to a "small hand pump", then clear hose off of that. normally some sort of "screw cap check valve" on the hand pump. that you squeeze or press a couple times to prime the line.
kerosene, diesel, gas they are rated for.
they have a long enough pipe on them to reach majority of 5 gallon jugs of fuel. toss the jug up on top of tractor. unscrew cap on jug, and toss in transfer pump. toss hose in gas tank, give it a few squeezes, and walk away, and it will drain all but last few sips of the jug.
============
google something like
kerosene transfer pump
stay away from the battery operated units, they end up being top heavy and cause jug to fall over once it is near empty. just a simple squeeze bulb or like about all you need.
