DEWAY Automatic Fuel Transfer Pump with Auto-Stop, 3X More Powerful D Battery Powered, Extra Long Hose Fits All Size Cans, Portable Liquid Pump Transfers at 2.4 Gal/Minute

Have used several of the tools. They really come in handy to put gas in a car, lawnmower, any gas product.

Transferring gas to pressure washer, my lawnmower and my Snow blower

The pump is easy to use and does a good job transferring liquids

This pump maybe did 20 gallons fo fuel, now it just spins and does not pump.Device eats batteries as well, put 4 sets of batteries in as well to do that small amount of fuel.Very disappointing for the price point.

Our use case so far has been 100% with our Honda Generator during winter storm related power outages. Up in the Sierra Nevada mountains of California where we live, these outages can last anywhere from 5-6 hours to as long as 18 straight days, as was the case during the Feb/March 2023 winter snow storms.The pump itself works great, as does the miniature "Gas Pump Style Handle". Beats the hell out of lifting, balancing and not dripping a full 5 gallon safety can of gas at 2AM, in sub freezing temps, while you are still half asleep!!!The only downside to this device is managing the pump after you are done fueling. The pump retains a about ¼ cup of gasoline inside of itself when you turn the pump off, so you can't just pull the thing out of the gas can without this residual gas dripping out of the Impeller end all over your patio, deck or garage floor.Over time, we have come up with a reasonable solution that works for us...DURING EXTENDED USE: (With something like a Generator during a power outage)Just leave the pump inserted into your gas can until that can is totally empty, or you are sure that you will not be pumping any more gas for the foreseeable future. (Power restored and generator no longer needed)AFTER FUELING IS COMPLETE AND IT IS TIME TO STORE THE PUMP:Before removing the pump from your gas can, try to shake the pump while the impeller is still inside the can and above the remaining fuel level to allow left over gas to drain out back into the can. Run the pump motor DRY for a few seconds if possible to pump out as much gas still left inside the pump itself and into the device you were previously refueling.STORAGE:We used the THUMB portion of a Latex Surgical Glove stretched over the pump's impeller end to catch any remaining gas that will be dripping out of that end of the pump over time, due to simple gravity. (There is no way to get every drop of gas out of the pump, so it will drip gas onto the area directly below where the pump is stored if you don't find some way to plug the impeller end) For us, it wasn't so much the volume of remaining gasoline, but the smell of this gasoline that we were trying to minimize.Our solution has worked out well for us so far. The one thing nobody mentions about these types of products is how to deal with the smelly liquid most of them will be pumping during normal use. ;o)
