Fuel tank rusting?

Hi guys just after a bit of advice my gti's off the road and i dont want my fuel tank to rust from the condensation build up. What should i do fill it up as its not got much fuel in at the moment. Or is there anything i can buy to put in the tank to protect it while its off the road?

Storing with a full tank of fuel stops condensation .

Cool do you think it will be alright after being off the road for a few months now without much fuel in the tank?

Months yes , its years you need to worry about .

Cheers ………….

Ok cool thanks mate.
