Abstract

A fuel system can include a main pump assembly (101) having a main fuel pump (103) connected to an input line and configured to pump fuel to a main fuel control (107) via a main fuel control line (109), a recirculation pump (111, 211) connected to the input line, and a fuel recirculation system (117) connected to the recirculation pump (111, 211) and upstream of the main fuel control (107). The fuel recirculation system (117) 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 (117) can be configured to recirculate fuel from the recirculation pump (111, 211) to a tank through one or more coolers in the recirculation mode, and to provide fuel to the main fuel control (107) in the backup mode.
