This is exactly what riv-nuts are for. A good local hardware store should be 
able to sell you a few fasteners and the simple handtool required to install 
them (that is, you don't necessarily need the adapted pop-rivet gun).

Facet makes a mounting kit for exactly this purpose - two rubber blocks, each of 
which has two studs molded in. One stud goes into the hole you make, one mounts 
the pump.

Using this kind of mounting is important for the life of the pump.
