Refilling FW: Bilge Pump!

In the 3 years we’ve had the T@B I’ve had to refill the 5-gal FW tank a number of times while boondocking.  Try lifting a 6gal can and you’ll only do the funnel thing once.  I had a cute little 2-AA battery pump...but it only worked one year before rusting out.  I’ve tried a portable drill pump...but, despite saying “self priming”, it often doesn’t prime.  We’re off to Utah this week for one last outing, and I hope we run out of water so I can use...my new bilge pump!  This one’s 36inches; I suppose I could’ve gotten a smaller one but I erred on the side of too long vs. too short for getting to the bottom of the 6gal spare water (plastic) can.  Anyone who’s used one in a sea kayak or boat knows how effective they move water....
