Up for sale is a Cornwell GS12050 GM Duramax Fuel Pressure Tester kit in the original case. This is a professional-grade diagnostic tool designed for GM Duramax diesel applications. The kit includes the items shown in the photos. It is in good cosmetic condition with normal signs of use. I have not tested or calibrated this tool, so it is being sold as used and untested.
