This set, used in association with AJDHU35026 or HU35026 , will allow to bypass the pump’s

regulator and measure the pressure to diagnose any regulator or pump issue

After observing the weak pump pressure : Simply remove the regulator and

choose the right dummy plug to bypass and seal the port. If the pressure comes

back to normal, the regulator causes the loss of pressure. If the pressure stays

too low, the pump is defective. This test is recommended by manufacturer of

high pressure pumps

Kit includes 8 different dummy to seal any regulator ports
