Flows like soup, perhaps, when it has no right (5)

'flows' is the definition.
(pouring is a kind of flowing)

'soup perhaps when it has no right' is the wordplay.
I cannot quite see how this works, but
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is located in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
The remaining letters 'pus' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'like' is the link.

Can you help me to learn more?
