This dummy regulators set is a must to determine if the pressure problem is the high pressure pump or the pressure regulator when there is no pressure at the outlet pressure port of the high pressure pump.
When replacing the pressure regulator by this dummy regulator we can determine quickly and effectively if the problem is due to the pressure regulator or to the high pressure pump. The test is performed as recommended by the manufacturer of high-pressure pumps.
The user must test that no there is no pressure at the high pressure pump outlet with the JOCR1600M tester or a similar device before replacing the regulator by the dummy regulator.
