OlexAzin Injector Tester

OlexAzin measures the fuel return flow. In a healthy system, all injectors should return roughly the same volume. By running the engine with all injectors connected to their own reservoir, any cylinder showing significantly higher or lower volume indicates a specific internal failure or imbalance.

The kit includes six complete sets of adapters for the four major OEM manufacturers: Bosch, Denso, Delphi, and Siemens. This covers almost all common rail injectors found in modern passenger vehicles and commercial light trucks.

No. The primary benefit of the OlexAzin kit is that it allows for in-situ testing while the injectors are still installed in the engine. You only need to disconnect the return lines to hook up the reservoirs, saving hours of disassembly labor.

Yes! While it is designed to accommodate up to 6 cylinders simultaneously for larger engines, it works perfectly for 4 and 5-cylinder engine configurations as well. Simply use the number of ports required for the vehicle you are testing.

Absolutely. We use high-grade copper for contact components to ensure conductivity and corrosion resistance, and chemical-resistant plastics for the reservoirs and connectors to ensure they won't cloud or degrade when exposed to fuels and workshop solvents.

Yes, the full kit comes in a heavy-duty, blow-molded carrying case to keep all adapters and reservoirs organized and protected from the harsh workshop environment.
