In connection with the Common Rail Kit (JM Nr.:6140868) you can use this set to bypass the governor of the pump in order to diagnose problems with the governor or the pump.
After diagnosing low pump pressure, simply remove the regulator and select the correct adapter from the box to bypass and seal the port.
If the pressure returns to normal after the test, the regulator will cause a pressure drop.
But if the pressure remains too low, the pump is faulty.
The test is recommended by the manufacturer of high pressure pumps.
The kit contains 8 different adapters to seal all controller connections.
