Supply Pump Removal/Installation - Mazda Mazda6 Workshop Manual Supplement

SUPPLY PUMP REMOVAL/INSTALLATION

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.
