'fuel found in crosby maybe essence that could lead to explosion' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'fuel found in crosby maybe essence' is the wordplay.
'fuel' becomes 'oil' (oil is a type of fuel).
'found in' is an insertion indicator.
'crosby maybe' becomes 'Bing' (singer Bing Crosby).
'essence' becomes 'point' (I've seen this in another clue).
'oil' placed inside 'bing' is 'boiling'.
'boiling'+'point'='BOILING-POINT'
