Will this pump work with my existing washer fluid hose and connectors?

Yes. The pump is designed to fit your stock reservoir setup without requiring hose modifications or adapter fittings. Inspect the outlet barb before installation to confirm it matches your current tubing diameter.

Do I need to drain the reservoir before swapping the pump?

Draining first prevents washer fluid spillage during removal and makes the job cleaner, but it's not required. If you skip it, have towels ready and work over a drain pan.

What tools do I need to install this?

Basic hand tools — socket set for the mounting bolts and a small flathead screwdriver to disconnect the electrical connector. No special pullers or lifts required.
