High Pressure Fuel Pump Removal/Installation: Notes

WARNING:

Fuel is very flammable liquid. If fuel spills or leaks from the pressurized fuel system, it will cause serious injury or death and facility breakage. Fuel can also irritate skin and eyes. To prevent this, always complete the "FUEL LINE SAFETY PROCEDURE ", while referring to "BEFORE SERVICE PRECAUTION".
A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before draining fuel, make sure to discharge static electricity by touching the vehicle body.
