Beschreibung
Zusammenfassung:	A fuel supply device supplying a fuel stored in a fuel tank to an engine includes a low-pressure pump configured to feed the fuel, a high-pressure pump configured to compress the fuel discharged from the low-pressure pump and to feed to the engine, a first low-pressure passage member configured to define a first fuel passage from the low-pressure pump to the high-pressure pump, and a second low-pressure passage member configured to define a second fuel passage branched from the first fuel passage at a low-pressure junction portion and joining the first fuel passage at a low-pressure confluence portion, wherein the first fuel passage and the second fuel passage are different in at least one of (i) temperatures of the fuels that flow through the fuel passages and (ii) passage lengths of the fuel passages from the low-pressure junction portion to the low-pressure confluence portion.
