If you're going to use the pump for several years, get the "higher end electric" pump.It's nice and fast, and you can replace the impeller if needed in the future. I tried cheaper pumps, but either they didn't work every well, didn't last, or were a hassel to use. The first time that I used the Topsider, the can dented. I guess that the diesel oil wasn't hot and thin enough. Spread out over many years, the cost of the pump is low. Of course, I use the pump on my boat motors, also.
