Dropping the pressure in the fuel system, petrol engine
 | After performing the following procedure, you just remove the excess pressure from the fuel system. The pipelines will be gasoline. Before disconnecting any fuel hose, take all the necessary precautions! |
Location service valve (1/1) for pressure relief fuel line gasoline engine The main components of fuel systems of gasoline engines are fuel tank disposed inside the fuel pump with the fuel supply sensor, fuel filter, injectors, pressure regulator, and a set of connecting lines. When the engine is running within the fuel supply path system is under pressure which persists for a sufficiently long period of time even after the ignition is switched off. Before disconnecting any of the components of the system pressure in bar should be reset. The simplest way to release the pressure in the fuel system is to start the engine when the extracted fuel pump fuse, - wait for spontaneous motor stop, then, to ensure the completeness of the pressure relief, rotate it several times a starter. If the engine fails to start, crank his starter for a few seconds. After finishing the procedure, turn the ignition off and return the removed fuse. At service stations in the supply pressure is released through the service valve located on a fuel distributive highway and working on the principle of a simple pin. Wrap a rag valve, remove the cap and press the nipple - do not forget at the end of the procedure to return the cap. Remember that after depressurization / removal of fuel from the power supply system at the start of the engine takes a few more than the usual time - have for a few seconds, turn the crankshaft starter as long as the system pressure is restored, and fuel fill all gasoline pipe lines.
