End fuel blending as required (7)

Ross

I believe the answer is:

needful

'required' is the definition.
(I know that required can be written as needful)

'end fuel blending' is the wordplay.
'blending' is an anagram indicator (letters blended or mixed into a new form).
'end'+'fuel'='endfuel'
'endfuel' is an anagram of 'NEEDFUL'.

'as' is the link.

(Other definitions for needful that I've seen before include "Necessary for nude elf" , "Nude elf (anag.)" , "Poverty-stricken" , "Requisite, necessary" , "Required" .)

I've seen this clue in The Globe and Mail.
