 PERFORMANCE ORDER

  1. At the working engine fuel in a path of a power supply system is under pressure which continues to remain during even rather long time after switching off of ignition. Before a detachment of any of components of system dump pressure in a step.
  2. The simplest way of dumping of pressure in a power supply system is start of the engine at the taken safety lock of the fuel pump or its disconnected socket, - wait for a spontaneous stop of the engine, then, for a guarantee of completeness of dumping of pressure, turn it several times a starter. If it is not possible to start the engine, turn it a starter within several seconds. Having finished the procedure, switch off ignition and return into place the removed safety lock or join the socket.
  3. Remember that after dropping pressure/removal of fuel the power supply system on start of the engine is left by slightly more time, than usually - it is necessary to turn within several seconds a bent shaft a starter until pressure in system is restored, and fuel will fill all fuel pipes.
