Product Features

  • Multifunctional Fuel Injection Cleaner Tool This injector cleaner tool can clean the entire fuel system, including the throttle valve, fuel nozzle and combustion chamber. At the same time, it also has a high and low pressure cleaning function to help you better complete the fuel system cleaning job.
  • Notes for Fuel System Cleaning Adapter KitThis product does not contain cleaning fluid. It is only suitable for gasoline injectors, not for diesel injectors. In addition, the connection method of the carburetor fuel system is the same as that of the electronic fuel injection system. But the pressure in the carburetor fuel system must be 0.07~0.35 kgf/cm2.
  • Disassembly-Free & Dual-System Fuel System Cleaner KitThe fuel system cleaner kit is used to clean the fuel injector, intake system and three-way catalytic converter. It can clean the car without disassembly. And it has two electronic fuel injection systems. One engine has an oil return pipe, and the other engine does not have an oil return pipe (Quick-connect anti-corrosion, anti-friction joints and anti-friction pipes for all cleaning fluids.)
  • Adjustment of Throttle Mode of Fuel Injector Cleaning KitThe connection method is the same, just adjust the air source pressure to 1-5PSI. How to identify the inlet and return hoses: Generally speaking, the larger the inlet pipe, the smaller the return pipe; There is always a filter interface on the side of the inlet hose and a buffer interface on the return side; There is an arrow on the hose Indicate the fuel flow direction.
