High pressure fuel pump (Mitsubishi Space Star)

Removal

• Disconnect the cable from the negative battery terminal.
• Remove the timing belt of the gas distribution mechanism drive.
• Disconnect the electrical connector from the high pressure fuel pump (Fig. 8.17).

• Disconnect the fuel supply and return hoses from the high-pressure fuel pump. Immediately after disconnecting the fuel supply and return hoses, as well as the high-pressure fuel line, be sure to plug any openings through which contaminants can enter the fuel system.
• Loosen the connecting nuts securing the high-pressure fuel pipe to the fuel pump and fuel distribution rail and remove the pipe.
• Using a special tool, block the high-pressure fuel pump pulley from turning and unscrew the pulley mounting bolt (Fig. 8.18).

• Remove the pulley from the high pressure fuel pump.

Installation

• Installation is carried out in the reverse order of removal, taking into account the following.
• Using a special tool, block the high-pressure fuel pump pulley from turning and tighten the pulley mounting bolt to a torque of 50 N·m (Fig. 8.18).
• Start the engine and check the fuel system for leaks.
