I may have found my issue. When I do a search for z32 injector images I get 2 types. One with the screens in the middle and ones with the screens near the base close to the lower oring. I have the type with the screens in the middle, which appear to be j30 injectors. With the adapters on and a tight cap installed, there is a sizable gap between the bottom of the adapter and injector cap. Is this normal or should they be touching? If the cap is what holds the oring in, I would think this gap is a bad thing. The gap is about 2-3 mm eyeballing it.
