I ordered both the Michigan Co. Cleaning product pump and the Mercury Marine gear lube pump.
The Mercury Marine pump was twice as much $23.93, compared to the MichCo pump $26.37 for two.
The MM pump does lock down in a closed position, but I think I like the cheaper MichCo pump. It pumps exactly 1oz each pump. 3 pumps, 3oz..
Man is this going to save time. No more measure cups to rinse, no more drips, no more spills. Two squirts in the back pack, 2 gal's H2O, and go!
Thanks again for the link Cola. PR
