• 【Main Functions】This cleaning kit can easily solve common problems such as injector blockage, leakage and insufficient combustion. This product can individually clean the injector removed from the engine, and you can clearly see the shape of the nozzle atomization to see if it is clogged or leaking oil. You can use this to save expensive nozzles when the injectors are clogged 【Wide Application】This DIY fuel injector cleaning adapter kit can easily clean the fuel injectors of most 12V-24V cars, motorcycles, electric vehicles, ATVs, boats, etc. Can be used with any off-engine fuel pressure gauge/tester, the injector tester is powered by a 12V battery adapter. Only suitable for gasoline vehicles, not suitable for diesel engines. It helps extend the life of your injectors and is a must-have for home mechanics 【How to Use】Turn off the vehicle engine and connect the black/red clips to the positive and negative poles of the battery (red is the positive pole and black is the negative pole). After the current is turned on, the solenoid valve in the nozzle opens. At the same time, the cleaning solution is flushed through the white tube and then through the injector for cleaning 【Protective Design】The 12V fuel injector cleaning kit is safe and practical. You don’t have to worry about safety issues caused by overvoltage or reverse voltage. When the injector is damaged or short-circuited, the injector voltage indicator light will flash. After power is turned on, when the injector starts working, the liquid pressure in the cleaning fluid bottle causes the cleaning fluid to spray out through the pipe, which can remove carbon deposits in the injector 【Package Included】After purchase, you will receive 2 alligator clip power cords (the length of the power cord is 34.6 inches) one with a large size plug and the other with a small size plug. 2 cleaning connectors (sizes 14mm and 11mm respectively) can install 2 different sizes of injectors
