not sure were i picked it up at.... it is a pump, that attaches to a wired/or cordless drill. has garden hose ends on both sides of it. rated for water, oils, diesel, (not regular gas).
also have a couple "hand siphon pumps" toss 5 gallon can of gas up on tractor, stick long hard tube down in can, then stick flex hose down in gas can on tractor, turn a little nob on top and a couple squeezes to start siphon and away it goes. same thing for 5 gallon bucket of oil. i only remember them for use in the old kerosone heaters used as extra heat in the winter, and fueling them up. till a few years back, and now use them for generator, and tractor, and dumping gas into a vehicle if need be.
my issue with the 2 hand lever pumps the others linked to, is they sputter and spit and drip oil during use. and a slight bump and hose falls out. granted always better than dealing with a variety of funnels and have an assortment at that, for what funnel works better without flipping over and spilling.
i might have to check to see if a sprayer pump (for spraying weeds and/or the lawn) can handle oils. more so the pumps with electronic pressure switch for use of a hand wand. for pressure on demand. 12v battery with a battery minder/charger hhmmsss....
