The dual pump that pumps water to the icemaker and water dispenser began leaking, so it needs to be replaced. I purchased a replacement (Part #67006531) but I have no experience with what appears to be three force fitting for connecting the pump inlet and outlets to the three plastic tubes.

I am unable to get the old pump off without cutting the tubing. Is there some trick I need to know to do this, or does it just need to be cut?

More importantly, when installing the new pump, how is the connection made? Is there a special tool or technique?

Thanks for any advice you can offer!
