Do I need any mounting hardware or connectors?

The pump assembly mounts at factory locations. Check your existing harness and reservoir connection before ordering — you may reuse OEM hardware if it's still functional.

Will this work if my old pump is stuck or seized?

Yes. This is a direct replacement. Remove the old pump from your reservoir, disconnect the electrical connector and hose, then swap in the new unit and reconnect both.

What if the spray pressure feels weak after installation?

Check that your fluid level is full and hoses are free of kinks or blockage. If pressure is still low, the nozzle jets may need cleaning — that's a separate maintenance item.
