Do you have to calibrate for a 330 g tank?

Works by the depth of the tank. Doesn't matter if the tank is 275 or 330 gallons or what ever as long as it's depth is 42" the scale will be accurate. Also has a scale for 24" deep tanks.

To the customer service department, can this gauge be use with hydrocarbons?

Presently using on 275 gal home heating oil tank . . . Seems to be working well and has good accuracy.

This gauge is not airtight but it is does not not have a vent in the conventional sense

Can this be used on gasolene?

I don't know if the parts will withstand the gasoline, but one other problem with this gauge is it is not fume tight. I have this installed on my heating oil tank and occasionally smell the heating oil odor if it is windy outside and it is definitely coming from the gauge housing.
