A rusty gas tank may also be responsible for the clogging of the fuel injector. With the help of the fuel injectors, fuel is being sprayed (in very tiny bits) into the combustion chamber.

As such, even the tiniest of impurities can pass from the gas into the main fuel injector. And for that reason, the rate of flow of the car injector can get blocked resulting in fuel injector clogging.

  • Connect the fuel line from the fuel injector cleaning kit to the fuel rail
  • Open the fuel line and power the engine.
  • Leave the engine to run until the fuel injector cleaning kit is empty.
