Awesome tool. Best feature is the fact that instead of running a pressurized gauge out from under the hood while on test drives, only the wires connecting the digital gauge to the adapter have to be routed outside. No more test drives with the hood only partially latched to keep from pinching hoses. The set I have has the Duramax feed adapter for suction vacuum readings.
Have had this set for many years now and can honestly say its been one of the best tools in my arsenal. Have used it to repair old brake lines and making a completely new set.
