Filling up again, could be a long ride? (9)

I believe the answer is:

reloading

'filling up again' is the definition.
('loading' is a kind of 'filling up' so perhaps 'reloading' is OK for 'filling up again')

'could be a long ride?' is the wordplay.
'could be' indicates an anagram.
'a'+'long'+'ride'='alongride'
'alongride' anagrammed gives 'RELOADING'.

(Another definition for reloading that I've seen is " charging again".)

I've seen this clue in The Independent.
