The reason for asking is that "a pump below the tank out" requirement will result in pump being fitted behind the front bumper 10cm from ground - I will obviously make some kind or dirt/water protection there but I imagine it will still be not good. If it's possible to locate the pump on top of the tank, then I may locate the tank behind the front bumper and the pump in the engine compartment (much safer / cleaner place).

The pump can normally prime itself few feet about the water level. But if you allow the water level to run so low that sucking in air is imminent, the system will not recover as quickly compared to a gravity fed setup.
If you are install the pump and relay in the engine bay area, make sure the water cannot trickle along the harness and work itself in to the relay and pump. Make a downward loop along the pump harness to avoid trickling water.
You must insulate the cable gland at the back of the pump with some silicon sealant. Plastic bag up the relay cluster is possible.
