I’ve been looking for a safe, spill-free way of filling my small engine fuel tanks. I’ve tried the gas cans with the on/off valve in the can spout. The first couple of uses it was fine but after a year of use the valve became difficult to use and it dripped gas onto the engine when filling. I even thought about making my own transfer pump using an old 12volt fuel pump and a couple hoses, but thought if the on/off switch were to spark it could be a disaster.
For a couple years now I have been looking at this Battery Operated Transfer Pump shown below but was hesitant to buy because so many of these inexpensive pumps are junk. This one doesn’t appear to be.
During Matthew the hurricane, I needed to fill the generator several times using a gas can I had a small spillage issue each time. After that hurricane it was time to order this Transfer Pump and see if it worked and was of reasonable quality.
Does it pump 5-6 quarts per minute as advertized?
Yes, and a lot more. For a flow test, I filled a five-quart jug in 24 seconds!
I used a five-gallon bucket with water and took this photo to show the stream of water the pump produces. That’s a ½ inch diameter stream that flows three gallons per minute.
The pump is designed to run off two, “D” size batteries. How many gallons will it pump on one set of batteries? I don’t know, but I did empty three five gallon buckets and was still pumping strong. “D” size batteries are expensive and I didn’t want to waste them for a duration test. I’m quite happy with this limited test, I’d guess the batteries could pump 50 gallons, far more than I would ever need for a hurricane season, I hope!
Pump Storage after use:
Because the pump impeller and fuel lines have no inline valves it will completely self-drain immediately after use. Just stand or hang it vertically and you’re done
What Do I like most of all about this pump?
It works, is spill free and easy to use.
For seasonal engine storage, I am now able to pump all the gas from the small engine fuel tanks into a larger 5-6 gallon storage gas can. Then run the small engine until what little is left in the tank is gone leaving the entire fuel system dry reducing possible fuel gumming-up in the carburetor and filters.
Best for small engine tanks and Portable Kerosene Heaters.
It appears to be a quality built product but only time will tell if it will last say 5+ years.
