Dropping pressure in fuel system

Before getting to work, get acquainted with the precautionary measures given in the Section General information and security measures.

After implementation of the procedure described below in pipelines there will be a gasoline. Before disconnecting any fuel hose, take all necessary precautionary measures.


  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.
