Force me to pull back and load fuel (4,2)

I believe the answer is:

fill up

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

'load fuel' is the definition.
'fill up' can be an answer for 'fuel' (thesaurus). I'm not certain of the 'load' bit.

'force me to pull back' is the wordplay.
'force' becomes 'F' (symbol used in Physics e.g. f=ma).
'me' becomes 'I'.
'to' is a charade indicator (letters next to each other).
'back' says the letters should be written in reverse.
'pull' written backwards gives 'llup'.
'f'+'i'+'llup'='FILL UP'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for fill up that I've seen before include "Occupy (some time)" , "Put petrol in car" .)
