I thank you for the recommendation Jimmy.

Not only is it easy to use and not expensive, no matter how careful I am with cans, the various (old) spouts and gaskets and plastic make some slop and leakage a virtual certainty every time you use one. But this thing did not spill or leak at all.
Not like I'm going to use it to fill my 2 stoke and lawn equipment, but I've also been slopping gas filling the smaller cans I use for those things from the full 5gal cans with a funnel. Now I can just line the small cans up and fill them all from 5's using the transfer pump leaky free once in a while.
