Final answer:
In a cruise with a center tank weighing less than 20,000 lbs but greater than 1,000 lbs, the fuel panel setup would involve turning on the boost pumps for main tanks 2 and 3, as well as both boost pumps for the center tank. All crossfeed valves should also be open. This setup ensures proper fuel distribution and flow.

Fuel Panel Setup:
For a center tank weighing less than 20,000 lbs but greater than 1,000 lbs in a cruise, the boost pumps for main tanks 2 and 3 should be turned on. Both boost pumps for the center tank should be turned on as well, and all crossfeed valves should be open.
This setup ensures proper fuel distribution and flow during the flight.
