SUPPLY PUMP REMOVAL/INSTALLATION [MZR-CD (RF Turbo)]

Caution

• Fuel line spills and leakage on the parts are dangerous. Fuel can ignite and also deteriorate the parts. To prevent this, always cover the mouths of the removed parts in the fuel system with rags to soak up the fuel.

• To prevent the fuel injection pipe from clogging, be careful that foreign material has not entered the pipe. Also, be sure to tighten the bolts with the specified tightening torque when installing the fuel injection pipe.

• To prevent fuel leakage, follow the procedure indicated in the workshop manual when removing and installing the fuel injector.

• The fuel injection pipe can be removed and reinstalled up to five times. Be sure to record in the service record when removing and installing the fuel injection pipe. If removing it for the sixth time, be sure to replace it with a new one.

• If fuel does not pass through the fuel filter, foreign material may have penetrated in the supply pump, and this may cause a malfunction resulting in damage to the supply pump. Therefore, do not install the fuel hoses (main and return side) in reverse. When installing the fuel hose, always follow the Fuel Hose Installation Note in the Workshop Manual and perform the procedure. (See Fuel Hose Installation Note.)
