Transported coal in another fuel container (6)

I believe the answer is:

oilcan

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

'fuel container' is the definition.

'transported coal in' is the wordplay.
'transported' indicates anagramming the letters.
'coal'+'in'='coalin'
'coalin' with letters rearranged gives 'OILCAN'.

'another' is the link.
This may not be right. It may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for oilcan that I've seen before include "Lubricator with a long nozzle" , "stops squeaking" , "Lubricant holder" , "Vessel for viscous liquid" , "Vessel for lubricant" .)

I've seen this clue in The Guardian.
