【Test 2 Injectors Simultaneously】Fuel injector cleaner tester can help you diagnose and clean injectors, easily identify common faults such as stuck, blocked, leaked or burnt-out conditions of the fuel injector. Compared with other fuel injector cleaner and tester with only one pair of pulse output terminals (black&red test lead), our fuel injector tester has 2 pairs of pulse output terminals, which can test two fuel injectors at the same time for comparison.
【8 Pulse Modes & Mode Lock Feature & LCD Display】The fuel injector tester kit is designed with LCD display and 8 pulse modes, which composed of 4 pulse signal output modes and 2 output voltage levels: Short/ Medium/ Long/ Continuous pulse modes + High/Low(12V/5V) power drive modes. Our fuel injector tester cleaner can drive almost all fuel injectors below 12V, except cylinder direct injection nozzles. You can choose any mode as your needs. And its mode lock feature ensures test condition uniformity.
【6 Size Adapters&Wide Compatibility】Our fuel injector cleaner kit comes with 6 size adapters: Φ9.8mm, Φ10.8mm, Φ11.8mm, Φ12.0mm, Φ13.5mm, M12, which compatible for almost all 5V and 12V vehicle injectors, for both EFI and GDI injectors. Our fuel injector tester cleaner is compatible with fuel injectors for VW, Audi, Ford, and most other models.
