Consumption is relatively smaller with turbofans as compared to piston engines or turbojets, but manufacturers generally use this to increase range rather than reduce fuel tank sizes. Flights no longer have to hop from Ireland to Newfoundland to cross the Atlantic, for example.

You can find images of large airliners being refueled - they absolutely dwarf the tanker trucks, which themselves carry 30 tonnes of fuel each. 100 tonnes looks about right.
