Aqua Pro 26300 water line replacement - need help pls

The model # is faded but I'm pretty sure i see 2 and a 300 in there so I'm guessing.
Anyway there is a small white plastic line that runs from the grey canister to the bottom of the pump. It has a drain valve at the end of it. Anyway the middle of the line broke. Trying to determine how to get it off the canister so I can replace it.......if i can find a replacement part! i have a photo but can't upload a picture because I'm new here so I can;t just yet.

Thanks in advance to anyone who replies.
