The Keimi cordless fuel transfer pump moves gas, diesel, or oil out of a can or drum through a hose and nozzle, running on an internal battery rather than a cord or a hand crank. Two features do the real work. The auto-stop sensor cuts the pump when the receiving tank fills, which is what prevents the classic spill down the side of a mower. The hand-trigger nozzle gives you gas-station-style control instead of the all-or-nothing flow of a siphon. Compared with tipping a five-gallon can, this removes both the lifting and the guesswork. It handles gasoline, diesel, and kerosene, and works for water transfer too. Best fit: mowers and generators, boats, tractors, ATVs, and anyone who has ever poured fuel down their own leg.
Pros
- Auto-stop sensor cuts the flow before the receiving tank overflows
- Hand-trigger nozzle gives gas-station control instead of siphon all-or-nothing
- Cordless, so it works in a field or on a boat with no outlet nearby
- Removes the lifting entirely, which matters with a full five-gallon can
Cons
- Fuel pumps need draining and airing out after use, so it demands more storage care than a plastic spout
Frequently asked questions
Does it work with diesel as well as gasoline?
Yes, it handles gasoline, diesel, and kerosene. It also works for water transfer, though you should not mix uses without thoroughly flushing it first.
How does the auto shut-off know when to stop?
A sensor in the nozzle detects when fuel reaches the fill neck and cuts the pump, the same principle a gas station nozzle uses. It prevents the overflow that siphons are notorious for.
How is it powered?
It has an internal rechargeable battery, so there is no cord and no separate battery pack to buy. Charge it before a job the way you would any cordless tool.
How fast does it pump?
Fast enough that a five-gallon can empties in a few minutes. Exact flow varies with fluid viscosity, so diesel moves more slowly than gasoline.
How should it be stored between uses?
Drain the hose and let it air out before storing. Leaving fuel sitting in the line is what degrades seals over time.
