A fuel delivery system for a gas turbine engine includes a fuel source and a main fuel pump configured to deliver a first flow of fuel to a combustor assembly of the gas turbine engine under a first fuel demand operating condition of the gas turbine engine. A secondary fuel pump is arranged in a fluidly parallel relationship with the main fuel pump. The secondary fuel pump is configured to deliver a second flow of fuel to the combustor assembly under a fuel demand second operating condition, different from the first fuel demand operating condition of the gas turbine engine.
