HF Compression Tester Mod PSD
Here is a pic of what's inside the HF (Harbor Freight) kit, minus one adapter that I used in my mod. to make it work for my '97. It may fit others as well, I have no idea what all the other adaptors are for. This kit does not come with an adapter for our trucks.
This is the adapter I made up from parts I bought at a local hardware store.
This is the brass reducer from the 1/8th NPT adapter to the 3/8 galvanized reducer.
This is the gavanized reducer that goes to 1/8th NPT to threaded rod.
I used a 3 1/2 in. long X 1/8th NPT threaded rod. I found this actually in the electrical department, it's used for installing or extending a light fixture from the ceiling.
Then I added a brass1/8th in coupler and about 1 1/2 in. brass threaded rod about 3 1/2 in. long. I thought the threaded brass was important because it is a softer metal than the threaded holes it threads into this would lessen the possibility of damaging the GP hole threads. I also didn't know if the glow plug holes were for sure 1/8 in. NPT, I really doubt International would use NPT pipe thread. However the 1/8th NPT threaded in easily.

yes the 6.9 and 7.3 idi are also m10 1.0. The HF kit has the right fitting but the quick connect is a 90 degree and doesn't fit between the rocker arm and the injector if I recall.
