A fuel system can include a main pump assembly having a main fuel pump connected to an input line and configured to pump fuel to a main fuel control via a main fuel control line, a recirculation pump connected to the input line, and a fuel recirculation system connected to the recirculation pump and upstream of the main fuel control. The fuel recirculation system can be configured to select a mode from a plurality of modes. The plurality of modes can include a recirculation mode and a backup mode. The fuel recirculation system can be configured to recirculate fuel from the recirculation pump to a tank through one or more coolers in the recirculation mode, and to provide fuel to the main fuel control in the backup mode.
