To return fuel to the engine from the injectors, a fuel overflow hose is used. It is an irreplaceable part of the fuel system. It is used to connect the components of the mechanism. Rings and union nuts ensure the tightness of the hoses. At the points of connection of the corresponding hoses, the nozzles and fittings have tapered holes.

The operation of the fuel overflow hose

To ensure the full functioning of any mechanism, the serviceability of each of its components is important. Such a detail as the injector fuel overflow hose is no exception. It connects low-pressure systems. As a rule, this part is made of thin-walled steel tubes. The hose is connected to the fuel supply point with hollow bolts and copper sealing washers.

The Dr.Motor Automotive brand Hose, fuel overflow removes excess fuel, which injects the corresponding mechanism. This is essential. After all, the pump at high pressure supplies fuel in excess. The engine speed, as well as the load on it, is systematically regulated and changed in a certain way. Therefore, it is almost impossible to predict the normalized amount of fuel.
