Will this pump work with my factory washer fluid reservoir?

Yes, it's designed as a direct bolt-in replacement. Your existing reservoir connects without modification.

Do I need any new hoses or connectors when I install this?

The pump uses factory hose diameters and connection points. Reuse your existing hoses unless they're cracked or kinked.

What if only the windshield sprayers work after installation?

Check that the headlight washer hose is properly seated on the secondary outlet. If fluid still doesn't reach the lights, inspect the hose for blockage.
