Check the rubber hoses for blockages or debris that might restrict water flow.

Reconnect the wiring to the new pump first while you have more space to maneuver.

Align the pump with the rubber grommets and press it forward to position the screw holes.

Secure the pump with the two screws, feeling for the threaded openings if working blind.

Reattach both hoses, ensuring the black hose notch is oriented correctly, then clamp them.
