Glacier Diesel Power | 2003-2007 Dodge Ram 5.9 Cummins Pressure Limiting Valve Isolator

Custom stainless fitting for correct isolation and testing of the Common Rail high pressure relief valve.

For proper testing this fitting is used to isolate the relief valve from the CP3 return line.

Please consult you Dodge service manual for correct testing procedures.
