Hand Pump 101

Do you guys use any water collector or dessicant bottle on your hand pump?

I did. I made a tall container about 30 cm tall x 8 cm in diameter using PVC tube and filled it up with silica gel. The container is connected to the intake of the pump via a hose. When the pump is not in use the container is detached and fully sealed to avoid absorbing unnecessary moisture. This is much better than that came with the Hill pump which is too small to be effective IMHO

Same here - there are a bunch of options for these on Amazon/eBay.
