ABSTRACT:
In a fuel supply device1in which high-pressure fuel in the inside of a common rail2which accumulates the high-pressure fuel supplied from a fuel pump6under pressure is supplied to an internal combustion engine by fuel injection valves, and the fuel pump6includes a plurality of high-pressure plungers61to64whose high-pressure-fuel injection timings are shifted from each other, a portion or all of high-pressure pipes11to14which connect fuel outlet ports6P1to6P4of high-pressure plungers61to64with the common rail2are connected with each other by connection pipes30to33thus establishing a state in which the high-pressure fuel from substantially one high-pressure plunger is supplied using the plurality of high-pressure pipes whereby the elevation of fuel pressures in the inside of the high-pressure pipes can be suppressed.
