\u2022 By switching the fuel pump discharge amount, reduced power consumption and improved fuel economy have been achieved.<\/div>\n
\u2022 The PCM determines the optimum fuel pump discharge amount according to the engine operation conditions, and sends the fuel pump drive signal to the fuel pump control module.<\/div>\n
