228bh sink drain flex hose replacement

[ayangch]

came back from a 4-day trip in mountains and noticed some water left on the floor. after checking around, found out the flex hose for sink drain line was broken. cut the broken part and the hose was not long enough so I have to buy a new one, but it seems not easy job to find one. the hose has a non-common size of 1-3/8", the local store normally has 1-1/4" or 1-1/2", googled online, saw one on Amazon for water fill hose, not sure if I can use it.
the one on amazon.ca:

just wondering if someone happens seeing this 1-3/8" flex hose before. attached is the flex hose (white one).

thanks.

I bought one at a camper dealership parts department. It seems to be fairly unique to campers.

I also had a pinhole leak develop in the sink drain line on my tent trailer. I purchased a replacement hose (1 3/8") from a local RV dealership for about $3 for a 4' hose. It was identical to the original that failed on the tent trailer.
