【Fuel Injector Tester and Cleaner Kit】PLAYOCCAR kit has 4 different sizes of blue tube adapters for 12V and below injectors such as EFI, GDI, FSI, MPFI, SPFI, TBI, CFI, L-JET, LPG, K-Jetronic, Coil-Over Direct Injection, Motorcycle Injectors etc. The cleaning adapter is used to connect the injector and car cleaning fluid for flushing, please switch off the engine before use. 【4 Nozzle Adapter & 8 Pulse Mode】The 12V automatic fuel injection pressure tester can be used with any fuel pressure tester to easily clean and test most fuel cars and motorcycle jets. In the continuous work of Mode 4, it can help determine whether the injection is good when the engine is closed. * Support cleaning and testing gasoline jets. 【Test 2 Fuel Injection at The Same Time】The injector cleaner tester can help you diagnose and clean the injector, and easily identify common faults of injectors, such as stuck, blocking, leakage or burning. Compared with other injectors and testers with only one pair of pulse output (black and red test wires), our injector tester has two pulse output terminals (two pairs of test wires), which can be tested at the same time Two injectors are compared. 【Polarity Anti Connection Protection & Short Circuit Protection】The fuel injector cleanser and tester have the function of input anti -connection protection and output short -circuit protection functions. When the injector is damaged or the pulse output terminal is short -circuited, the power indicator light of the injector cleaning tool will flash the prompt. 【40" Power Cord & 20" Test Cord】The power line is up to 40 inches/100 cm, and the test line is up to 20 inches, which is more convenient for you to connect and use it. The wire is made of high -quality silicone, which has better high temperature resistance and low temperature resistance. The fuel injection cleaning set is powered by a 12V battery or an external DC 12V (recommended at least 1.5A) power adapter. It can work in the case of the engine that is off -the -shelf, and can be used with any fuel pressure tester (note: only gasoline vehicles, not suitable for diesel engines) This instrument can help you diagnose injector problems and can be used to test injectors one by one or two at the same time to help confirm sticking, leaking, damage or burnout conditions. It has 2 output voltage levels and 4 pulse signal output modes. Users can choose any one according to their needs. It uses the 12V battery on the vehicle or an external DC 12V (recommended at least 1.5A) power adapter as the power supply to work continuously. Mode helps identify good and bad injectors with the engine off. This instrument can be used with any fuel pressure tester.
