COMMON RAIL HIGH PRESSURE TESTER
DESCRIPTION
The tester you have just purchased is an essential tool for proper diagnosis of the common rail injection system.
When a common rail engine has problems starting or running, the first parameter you should measure is the pressure in the high
pressure circuit.
Most of the testers that are currently available in the market do not actually measure the real pressure; instead, they take the
signal from the pressure sensor installed in the vehicle itself and show a pressure based on the pressure read by that sensor.
This tester can check the real pressure in the high pressure circuits in common rail systems using a high pressure gauge (2000
bar) and high pressure hoses.
The tester is equipped with a pressure release valve which allows the maximum pressure produced by the pump to be tested.
The hoses make simple connection to the injection system possible.

Engine running test
Using this tester is extremely simple. You must replace one of the high pressure pipes with the tester fitted with two hoses, so
that you can check the circuit pressure while the engine is running.
The connection is usually made by replacing the high pressure pipe from the high pressure pump to the injection rail.
In some vehicles, access to the high pressure pump may be difficult; in that case, the connection can be made by replacing
any pipe connecting the injection rail to the injectors, since the pressure is the same at any point in the high pressure circuit.
All the pipes shown in the following figure (Fig. 1) can be replaced by the high pressure tester.
To connect the tester properly, follow these steps:
• Locate an easy-to-access high pressure pipe.
• Loose and remove the pipe connections. The pipe should be stored in a place where it cannot get dirty, because any dirt
coming into the injection circuit may damage the injection system.
• Choose the appropriate hoses, according to the threads of the connectors of the vehicle. The thread can be either M12x150
or M14x150.
• Ensure they are free of dirt, to prevent particles from entering the injection system, and mount the hose in the “T” sensor, so
that you get a set like Fig. 2.
