Part needed - jbj nanocube 28

[VintageReefer]

I have an old compact fluorescent jbj nano cube 28 I pulled from storage and I replaced the 2 pumps and return tubing, but I am missing a 90 degree slip fitting that goes in the rear return bulkhead. I can’t find this anywhere. I found what I thought would work, link below, ordered it, and it’s the right size for the tubing but it’s slightly narrower than the oem connector and it doesn’t sit snug in the bulkhead and slides right out. Compared to the oem that I do have, it is in fact slightly narrower.

Does anyone know a compatible part to match oem that will fit? Can this be ordered from jbj or does anyone make a dupe?

Reminder: this is in my possession and is not compatible need suggestions other than this:

I notified the seller and they did offer to return it and said this is the only one they carry for a nano cube 28.
