This is a Brand New Tool

Set of 8 Dummy Regulator replacements for use with a high pressure tester for Common Rail Diesel Engines - DM-CR1600M

Once the rail pressure is tested and found as a fault, these dummy plugs can be used to replace the regulator to determine if the fault is in the fuel regulator or the high pressure pump.

Only for use with a high pressure tester that is equipped with an over-pressure relief valve.
