Will this pump handle both the front and rear windshield washers?

Yes. The assembly feeds both circuits through the single pump outlet — front and rear washer nozzles pull from the same pump.

What fasteners or connectors do I need to mount this?

The pump slides into the factory reservoir clips — no additional hardware is needed. You'll connect the existing hose and electrical connector from your old pump to this one.

Does the white finish need sealing before installation?

The housing sits inside the washer fluid reservoir, so it's submerged. Paint or protective coating is not required for function or longevity.
