A fuel supply apparatus restrains occurrence of resonance at a connecting portion of a distal end of a low-pressure fuel intake pipe to thereby reduce surges in fuel pressure and control generation of noises. The fuel supply apparatus includes: a fuel tank; a low-pressure fuel pump provided in the fuel tank; a low-pressure fuel intake pipe having one end thereof connected to the low-pressure fuel pump; a first branch pipe having one end thereof connected to the other end of the low-pressure fuel intake pipe; a first high-pressure fuel supply assembly connected to the other end of the first branch pipe, and which pressurizes a low-pressure fuel into a high-pressure fuel and discharges the high-pressure fuel; a second branch pipe having one end thereof connected to the other end of the low-pressure fuel intake pipe; and a second high-pressure fuel supply assembly connected to the other end of the second branch pipe, and which pressurizes a low-pressure fuel from the low-pressure fuel intake pipe into a high-pressure fuel and discharges the high-pressure fuel, wherein the first branch pipe and the second branch pipe are composed of steel pipes.
