Sbrasyvaniye of pressure in a power supply system

Before starting to work, attentively familiarize with the preventions stated in the section Power supply system - petrol models. Remember that performance of this procedure allows to dump only partially pressure in a fuel path of a power supply system, residual pressure continues to be present at lines - be careful when undocking shtutserny knots.

The number of components of a power supply system considered in the present section includes the gasoline pump established in a fuel tank, the fuel filter, injection injectors, the fuel highway with a regulator of pressure of fuel and connecting components metal tubes and flexible hoses. In all listed components at the working engine and/or the included ignition there is a fuel which was under pressure. After ignition switching off fuel continues to remain under pressure during even some time. This pressure before performance of any repair or preventive work connected by undocking of a path, should be dumped safely.


1. Disconnect a negative wire from the battery.
2. Get drain capacity under shtutserny connection subject to undocking. Prepare rags for collecting fuel spilled by capacity.
3. Slowly weaken the shtutserny socket / a cap nut of connection, then wrap up knot rags after residual pressure in a path will be dumped, is final расстыкуйте knot and disconnect the fuel line. At once закупорьте the open ends of the tube/union for the purpose of minimization of losses of fuel and in order to avoid hit in a dirt power supply system.
