Desirous of managing the fuel to go to the dance (7)
I believe the answer is:
hopeful
'desirous' is the definition.
(thesaurus)
'managing the fuel to go to the dance' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'fuel' is 'eful' which is located in the answer.
'dance' could be 'hop' (hop is a kind of dance) and 'hop' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for hopeful that I've seen before include "Optimistic, expectant" , "One wishing to succeed" , "Wannabe" , "Prospect" , "Promising success" .)
