Narrative:

Climbing out of approximately FL200; we observed the master caution fuel light illuminate; and assumed our center tank was empty. I was the pilot monitoring; and I was surprised to see that we still had approximately 2300 lbs of fuel in the center tank with an associated 'configuration' fuel message on our fuel totalizer. As looked up to our fuel panel switches; I saw both fuel pumps on with both low pressure amber lights on. I thought that maybe there was some sort of electrical glitch; so I selected both center fuel pumps off; and then back to on; with no change in the initial condition. I then pulled out the QRH; and referenced 'configuration' checklist. It stated that the checklist be completed in level flight; so I waited until we reached our cruising altitude of 37000 ft. Once there; we completed the QRH with once again no change in the initial condition. Thinking that maybe we had a circuit breaker popped; I checked for circuit breakers so that [maintenance control] would be notified once we got to a repair station. After a thorough look I found nothing. We then we got a phone patch through airinc to contact dispatch and [maintenance control]; to see if they had any suggestions for us try. They had none. We then discussed if we would continue or divert to another airport; and after taking all options into consideration; we elected to continue to ZZZ. We did ask the ATC desk to see if they could give priority into ZZZ over other aircraft; which they did; and we landed in ZZZ five minutes ahead of schedule. Once I the gate; we still had approximately 1600 lbs of fuel in the center tank with the 'configuration' message on the fuel totalizer; and the low pressure fuel pumps lights still illuminated any time the center fuel pump switches were selected to 'on'. We started with 2300 lbs in the center tank at the beginning of the event; and ended at gate with 1600 lbs in the center tank; so it seems that we did get approximately 700 lbs out of it; even white these low pressure lights illuminated; when the switches were selected 'on'.

Narrative: Climbing out of approximately FL200; we observed the Master Caution Fuel Light Illuminate; and assumed our Center Tank was empty. I was the pilot monitoring; and I was surprised to see that we still had approximately 2300 lbs of Fuel in the Center Tank with an associated 'CONFIG' Fuel Message on our fuel totalizer. As looked up to our fuel panel switches; I saw both fuel pumps on with both low pressure amber lights on.
