It really looks like it does. I say it is the adapter at the far right

I picked up a kit from there and, on mine, I had to modify the adapter because it was too long. Bring a spare glowplug to compare it. Other than that it works good.

OK give me hell, bought mine on e-bay 21.50 +15.00 shipping has more adapters and works fine.

I bought this one and none of the glowplug adapters would fit. The diameter of the "stem" is bigger than the diameter of the hot end of a glowplug, so it wouldn't drop in far enough for the threads to engage.

I didn't want to modify any of the parts, and it just so happens that the hole in the top of their injector adapters is the same diameter and thread as the glowplugs. So I just used the little nipple that is meant to be screwed into the injector adapters that come with the kit, and screwed the nipple directly into the glowplug holes in my engine heads.

Kind of a pain to get the hose from the guage snapped onto the nipple once it is screwed into the head, but it is do-able, and works just fine.
