| but it's also possible we are talking about differing methods of manufacturing design? Take a look below at these two photos from the one I pulled apart. The plastic can holding the coil fit loosely into the body of the injector as did the metal center sleeve. There is no doubt in my mind that for my style of injector design - gasoline was able to come up via the center of the Coil Can (as well as the sides) and into contact with the grommets. In addition, given the way the top metal cap is crimped to the injector's body and then the whole thing is covered with the red upper plastic -- I have doubts about how much moisture could actually get into the grommet area from topside. I do think you've nailed it regarding the solder joint failure issue -- so it's really just a matter of what we believe is driving that problem to happen (moisture, ethanol or a combo of both?)...
