Is ITC available on tank lorry?

If I buy a tank lorry for my petrol pump business, will the ITC be available for utilisation?

It will be used for transportation, no doubt. But the transportation will be that of petrol and diesel which are presently outside the purview of GST? So, no GST goods will be transported by the tank lorry.

Will GST be still claimable in that case? Or it has to be reversed?
