Stuffed as stormy petrel snagged the end of the line (7)
I believe the answer is:
replete
'stuffed' is the definition.
(I've seen this in another clue)
'stormy petrel snagged the end of the line' is the wordplay.
'stormy' is an anagram indicator (stormy suggests disruption).
'snagged' indicates putting letters inside.
'the end of the' says to take the final letters.
The final letter of 'line' is 'e'.
'petrel' with letters rearranged gives 'replte'.
'replte' placed around 'e' is 'REPLETE'.
'as' is the link.
(Other definitions for replete that I've seen before include "Well-supplied" , "Filled, well supplied" , "Full, sated" , "Filled, sated" , "Chock-a-block" .)
