Common Rail Return Flow Pressure Tester
PARTS
• Pressure gauge for Bosch and VDO Siemens Piezo-Injectors, measuring range: -1 to +15 bar
• Pressure gauge for Delphi Piezo-Injectors, measuring range: -1 to +3 bar
• Transparent body with drain valve for visual inspection for air bubbles, two quick couplings and
drain hose

INTENDED USE
This test tool set is made for testing the return flow pressure from common rail injectors of Bosch,
VDO / Siemens and Delphi. The determined pressure values allow a condition assessment of the
piezo injectors.
SAFETY ADVICE
• Due to the extremely high working fuel pressures in the common rail fuel system, NEVER
slacken fuel or injector pipes or try to disconnect components of the fuel system whilst the
engine is running and high pressure is present in the system!
• Avoid skin and eye contact with fuels. When you working with fuels always wear fuel-resistant
gloves and safety glasses!
• Do not work in areas where there is an open flame or fire.
• Never ignite a match or other flammable material near the engine.
• When testing fuel systems, do not operate electrically powered tools or other equipment that
could cause a spark.
• Let the engine cool down before you start testing the fuel system.
• Replace leaking or cracked fuel lines and connections.
• Keep children away from the work area and never allow them to play with the tool or its
packaging.
• Do not smoke during inspection work on the fuel system.
