Will this pump work with my existing hoses and connectors?

Yes — this is a direct replacement for your RDX, so it uses the same connector and hose fitments as the original. No adapter or modification needed.

Do I need to drain the reservoir before installation?

It's a good idea to empty or mostly drain the fluid first — makes the job cleaner and prevents spill. Not required, but less mess that way.

What warranty or return window applies to this pump?

Standard return window applies from your purchase date — test the pump immediately after install to confirm spray function. If it fails to pressurize or spray within that window, you're covered.
