PROBLEM TO BE SOLVED: To provide a fuel supply device for an engine capable of suitably suppressing generation of vapor due to shortage of fuel supply quantity to a high pressure fuel pump. SOLUTION: This fuel supply device 5 is provided with a cylinder injection injector DI injecting fuel to a combustion chamber 23 and a port injection injector PI injecting fuel to an intake port 33, pressurizes fuel delivered from a low pressure pump 52 by a high pressure fuel pump 53 and supplies the same to a fuel distribution pipe 54 for cylinder injection and regulates pressure of fuel in the fuel distribution pipe 54 for cylinder injection at cylinder injection pressure or less by a pressure regulating valve 56 for cylinder injection. And a communication fuel pipe RE connecting an outlet side port 56B of the pressure regulating valve 56 for cylinder injection and an upstream side of a fuel distribution pipe 55 for port injection and a pressure regulating valve 57 for port injection regulating pressure of fuel in the fuel distribution pipe 55 for port injection at port injection pressure PB lower than cylinder injection pressure or less are provided.
