loc-line

Can you identify the size and type of the nozzle, tube and the size of the bulkhead? Need to buy something identical.

Can anyone for sure tell me what size loc-line this is? I have been told 3/4" and 1" . It obviously measures 1" inside diameter on the female end but I don't know if they rate these at this end or the other. I need to buy some more pieces to complete what I am trying to do but not sure what size...
