Simple question, I hope. I keep three 5-gallon gasoline jerry cans in my garage to fuel my generator. I'm trying to rotate the gas in one can out every six months into my wife's car so I can refresh it. But it's a major pain trying to lift that can up and pour it (oh so slowly) into the tank. I bought a cheap siphon at Lowe's and it worked as well as you'd expect -- that it, it didn't, and broke easily.

I'd really like to get something industrial grade, with perhaps a hand crank, reliable, reusable, etc. Any suggestions? Thanks in advance. -Gary
