Is the little pump you're considering an on-demand pump with a pressure switch, or one that would run continually (or try to)? You want an on-demand pump.
Electronics Goldmine has some good prices on appropriate pumps: 1.9 gpm for $40 or 2.9 gpm for $45 plus perhaps a bit more necessary fittings. I think either of these would be rather more satisfactory than a 1.2 gpm pump.
The one I looked at was on demand.

thank you for the links to the other ones. I will have to consider those also. Although with shipping, they are over $60. Still not much money though.
