5.2.13. Fuel nozzles
Prevention
When checking work of fuel nozzles never hold up hands or any part of a body under the fuel stream leaving a nozzle. Fuel comes out a nozzle under high pressure and can get into a body through skin that can lead to a fatal outcome.
Check
Parameters of a nozzle worsen at long use and, most likely, they need to be repaired or replaced after 100 000 km of a run of the car. Check, capital repairs and calibration of nozzles have to be made by the expert.
