Developed in the 1980's as a concentrated cleaner formulated to clean fuel injectors on gasoline engines. It is a disposable pressurized can that requires specialized hardware to administer. It is designed to be attached directly to the engine fuel system with appropriate 3M™ adapters and hardware. When connected properly, the engine runs on the contents of the can. For best results, use this product together with 3M™ Fuel Injector Cleaner Tank Additive 08812 and an aerosol can of 3M™ Throttle Plate and Intake Cleaner 08866. Application instructions are vehicle specific. You should refer to the 3M™ Fuel System Cleaning Application Guide, CD-ROM, 08816 for detailed directions.
