How to remove the fuel injector?

1. Remove the fuel rail, remove the fuel injector, clean the carbon deposit at the inlet and outlet of the fuel injector with carburetor cleaner, and then apply a voltage of 12V to the fuel injector. Connect the thin tube of carburetor cleaner to the inlet of the fuel injector. If it is too thin, it can be wrapped in vinyl cloth to thicken it. One person can hold it with both hands to ensure that the carburetor cleaner and the injector inlet do not leak oil, and the other person can jog the power supply of 12V to make the cleaner spray intermittently until the oil mist sprayed by the injector is fine and uniform.

Second, pay attention to the installation of the rubber sealing ring of the fuel injector, so as not to be damaged by aging. The oil mist sprayed by the unwashed injector is like rain, and the oil mist sprayed by the washed injector is like fog. After installing the injector, observe whether the upper and lower sealing rings of the injector leak oil, and no gasoline can leak.
