Injector Leak Off Tester 6 Cylinder Common Rail Diesel Kit

An injector leak off tester kit for checking return flow on common rail diesel systems across up to 6 cylinders. Used to measure the amount of fuel each injector returns to the deposit tank, helping identify imbalance or injector-related faults during diagnosis.

Used for vehicle maintenance, diesel fault finding and servicing work, this type of kit is handy when tracking poor running, hard starting, uneven idle or suspected injector problems. Suitable for garage work, workshop use and experienced home mechanics working on common rail diesel vehicles, especially where injector performance needs to be compared across several cylinders.

The kit is supplied as a flow meter and adaptor set for use on up to 6 injectors, making it suitable for multi-cylinder testing without needing to swap parts between every check. Adaptors are included for Bosch, Siemens, Denso and Delphi injectors, covering several common diesel fuel system setups. For regular diagnostic work, that makes it a practical way to check injector return rates more efficiently and keep the testing process straightforward. The multi-cylinder layout is also useful when comparing injector behaviour side by side during servicing or fault diagnosis.
