intrepidvoyager I regularly operate a 179nm sector in a B717-200, both engines 18k & 21.5K. Fuel burn ranges from 1400kg to 1900kg, depending upon the usual variables of wind & weight. Even landing at gross weight (49.895k) at ISA +15, with a 60kt HWC, the highest burn I've seen is 1900kg (2400l; 529 imperial gallons, 634 US gallons).
