Yes, you have the hoses attached correctly.

Those pumps are not self priming, so they cannot pull any water if they are currently filled with air. It is probably best to locate the pump at about the same height as the bottom of the fluid reservoir. Doing that, and priming the supply line the first time should get it working for you. Mine is probably located about 6 inches further down into the engine compartment than yours is in the photo.
