Remove filter strainer with a wood screw and pull it out. Once a filter be pulled out like this, it will be damaged and we have to replace it with a new one.


DIY adapter: a hose that fits on the fuel injector glued to a car cleaner straw and use hose clamp to prevent it from popping out

Use wire with elevator clip 12 volt battery since fuel injectors need power to open and close the solenoid.

You can use your cars battery as well. Sometimes we used to use 9 volt batteries , you should be able to hear the clicking sound of the solenoid. We made a wire whit a push switch for better operation it.
