You can work out the details for just about any combination using the F-4 range table at Beim Zeugmeister - the G-6 had very similiar :

It should be pretty simply assume a full tank, as in your example, of 400 liters. Say 3 minutes is spent on maximum power, 1475 PS, that is 480 lit consumption per hour, or 24 liters in 3 minutes. Say another 10 minutes is spent 30 minute rating - 400 liters/h - which is another 67 liter consumed. That is 91 liter in total, leaving 309 liters for other purposes.

The F-4, at the engine power best for range consumed 120 liter/h, and could fly 315 km/h at 1 km altitude while doing so. 309/120 is 2,57 h duration, during which the aircraft can cover 2,57 x 315 = 811 km. So, about 400 km radius in an optimum case, or 300 km radius for a pretty safe bet.
