I'm a little stuck... Click here to teach me more about this clue!

'fuel gauge' is the definition.
'dipstick' can be an answer for 'gauge' (dipstick is a kind of gauge). I'm not certain of the 'fuel' bit.

'tips off richard about' is the wordplay.
'off' indicates an anagram.
'richard' becomes 'dick' (Dick can be a nickname for Richard).
'about' means one lot of letters goes inside another.
'tips' is an anagram of 'psti'.
'psti' placed within 'dick' is 'DIPSTICK'.
