See lid designed for fuel (6)
I believe the answer is:
diesel
'fuel' is the definition.
(diesel fuel is a kind of fuel)
'see lid designed' is the wordplay.
'designed' indicates an anagram (designed with the letters).
'see'+'lid'='seelid'
'seelid' anagrammed gives 'DIESEL'.
'for' acts as a link.
(Other definitions for diesel that I've seen before include "Rudolf __ , French-born German engine inventor, d.1913" , "Type of engine" , "Engine fuel" , "Liquid fuel" , "Kind of engine" .)
