This professional tool set has been specifically developed for the precise measurement of the leak-off pressure (return flow pressure) of modern Common Rail (CR) injectors, with special consideration for units equipped with Piezo technology. This category of diagnostic tools is essential for ensuring the efficiency and reliability of diesel injection systems, enabling workshops to quickly identify excessive return flow, which can be a sign of injector failure.
The set consists of outstanding quality components that guarantee a long service life and reliable, repeatable measurement results even in the most demanding workshop environments. Due to the specific design of Piezo injectors, conventional measurement methods are often inaccurate; therefore, this dedicated set provides the optimal solution for determining the precise leak-off flow rate.

Measuring the leak-off flow rate is critically important in the maintenance of Common Rail systems. If an injector returns too much fuel to the tank (excessive return flow), it means the injector cannot properly regulate the amount of fuel injected, which leads to:
For power loss results, as insufficient fuel reaches the main injection cycle.
For increased fuel consumption contributes to it.
For damage to the catalytic converter and particulate filter (DPF) can result due to improper combustion.
This dedicated measuring tool allows the technician to test injectors individually and compare the measured values with the specifications prescribed by the manufacturer. Quick and accurate diagnosis reduces unnecessary parts replacements and increases the efficiency of the repair process.
This leak-off pressure gauge set perfectly complements the following tools related to fuel injection systems, which are also available in our range:
