Fuel running short as tugs perhaps crossing N Asian landmark (8,6)
I believe the answer is:
petronas towers
'asian landmark' is the definition.
(Malaysian skyscrapers)
'fuel running short as tugs perhaps crossing n' is the wordplay.
'fuel running short' becomes 'petro' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'tugs perhaps' becomes 'towers' (tugboats tow things along).
'crossing' means one lot of letters goes inside another (to cross can mean to go over or around).
'petro'+'as'+'towers'='petroastowers'
'petroastowers' going around 'n' is 'PETRONAS TOWERS'.
(Another definition for petronas towers that I've seen is " Kuala Lumpur landmark".)
