Wine bottles bloke endlessly passed round university, topped up again (9)
I believe the answer is:
refuelled
'topped up again' is the definition.
'wine bottles bloke endlessly passed' is the wordplay.
'wine' becomes 'refel' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bottles' indicates putting letters inside ('bottle' can mean to contain).
'bloke' becomes 'guy' (I've seen this before).
'endlessly' says to take the centre (the ends of the words are removed).
'passed' becomes 'led' (leading is a kind of passing).
The middle letter of 'guy' is 'u'.
'refel' going around 'u' is 'refuel'.
'refuel'+'led'='REFUELLED'
'round university' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
