525 G2 Return Plumbing

[AMDman13]

Does anyone know what the actual size is of the return plumbing on a G2 525? It looks to be 3/4". I have reached out to tech support and I am getting conflicting info. I apologize if this has already been discussed. I have searched and searched, but everything points to previous generation of Reefers.

It's 3/4" for each of the returns on my 750XXL v3. Note that it's probably in metric, though.
