... as for how much water the pump consumes, it's easy... You fill completely (to the top) the windshield washer tank and you measure how much you have to add to fill it up again after.

I came to the conclusion of a water tank size of 5.5"x11"x7.5". goes where the battery used to be. fabricated out of aluminum with a baffle. We'll see how it works out.
