Tilted the washer so it leaned forward and propped it up on something sturdy as the washer is in a tight area. I pulled the metal clips from the ends and because I was in a very tight space, resorted to using a utility knife to cut the old leaking tube off one side and was able to wiggle the end connecting to the underside of the washtub off. A small butterknife was helpful to release the sealant. The most challenging part was wiggling the new tube into the place under the washtub and getting the clip up to the ring on the tube it nestles into.
Again, it is a tight space that'd required me to remove a toilet or a small sink vanity to pull the washer out enough to have room to work. I'm a smaller size female with average strength and I did this by myself-it's a VERY do-able fix.
There was a bit of sealant used to install the tube but this washer was left by the previous owners so I'm not sure if it's been replaced before ( according to Q&A with this part sealant is not necessary and is not often used by manufacturers.
I've washed 3 loads of laundry and there hasn't been a drop of water leaking.
