Safety Precautions When Working On Fuel Supply System
There is a risk of injury due to the fuel being under pressure.
The fuel system is under pressure. Injuries are possible from fuel spraying out.
Before opening the fuel system:
-- Wear protective eyewear.

-- Reduce the pressure: place clean cloths around the connection point and carefully open the connection point.
Risk of a fire due to leaking fuel.
