CMTOOL Fuel Injector Tester & Cleaner Kit — 6 Adapters, 8 Pulse Modes, 12V/5V Output

Overview

The CMTOOL Fuel Injector Tester and Cleaner Tool Kit is engineered for DIY enthusiasts and pros alike. With a strengthened adapter set and a versatile pulse toolkit, it helps you assess injector performance, spot irregularities, and prepare components for reliable reassembly—without removing the engine unless you choose to verify operation.

Broad compatibility and adaptable cleaning

The kit ships with six cleaning adapters of different sizes, tailoring coverage for 12V and below injectors across a wide range of technologies. This includes EFI, GDI, FSI, MPFI, SPFI, TBI, CFI, L‑JET, LPG, K‑Jetronic, coil‑type direct systems, and various motorcycle injectors. In practice, this means you can tailor your setup to the injector geometry you’re working with, reducing guesswork during diagnostics and maintenance.

• Six sizes of cleaning adapters help you match a broad spectrum of injector profiles.
• Compatibility spans many 12V automotive and motorcycle injection systems, supporting both gasoline engines and transitional tech families.
• Designed to assist in diagnosing injector performance and identifying potential faults before they impact engine idle and power delivery.

Flexible testing options

Operating the tester is straightforward, with eight pulse modes plus two voltage drive levels. The LCD clearly displays your selected mode, and indicator lights confirm the pulse output status. The ability to run four pulse outputs across two test leads provides a practical setup for evaluating multiple injectors in a controlled environment.

• 8 pulse modes include short, medium, long, and continuous pulses, with 12V or 5V drive levels.
• Two injector testing at once is possible via four output terminals and long, robust test leads.
• Two indicator lights offer quick visual feedback during operation.

Safety and power options

Safety features help protect both the tester and the user. The unit includes reverse polarity protection and short circuit protection, reducing risk during setup or fault testing. It is powered by a 12V vehicle battery or an external DC 12V adapter (recommended at least 1.5A). Note that the kit does not include a power supply or cleaning agents.

• Reverse polarity protection helps prevent accidental damage during clamp connections.
• Short circuit protection adds a layer of safety during testing sessions.
• Power can come from a 12V battery or a dedicated 12V DC adapter; cleaning agents are not included.

Real-world use and benefits

In everyday use, you can simulate injector operation, compare injector response before and after cleaning, and confirm consistent signal behavior across pairs of injectors. The combination of multiple adapters and varied pulse patterns supports a hands‑on approach to troubleshooting, rather than relying on guesses. While the kit cannot guarantee engine performance, it offers a practical, repeatable method to gather actionable insights during maintenance and repair projects.

Notes and setup considerations

• The kit is intended for gasoline engines and should not be used with diesel systems.
• Power supplies and cleaning agents are not included; ensure you have a compatible 12V source ready before use.
• The package includes adapters and leads required for testing; check compatibility with your injector type before connecting.
