PROBLEM TO BE SOLVED: To provide a fuel supply system for a fuel-injection type engine in which a pressure check of a fuel pre-pressurizing system and a highly pressurizing system can be performed by one checking means and a maintenance work is not cumbersome. SOLUTION: A fuel supply system for a fuel-injection type engine has a fuel pre-pressurizing system 15 for pre-pressurizing fuel from a fuel tank 17 to a predetermined pressure and a fuel highly pressurizing system 14 for pressuring the fuel from the pre-pressure fuel system 15 to an injection pressure. When a high pressure engine-driven pump 33 of the fuel highly pressurizing system 14 is not operated normally, it can transmit the pressure of the fuel pre- pressurizing system 15 to the fuel highly pressurizing system 14 and the fuel highly pressurizing system 14 is provided with a pressure checking means. |
