    My injector cups went out two times, in less than two years. It has something to do with what they are made of. The first time they were replaced, I was in Fontana,CA. This caused about 4 days down time. Evidently, they did not use ceramic injector cups, and I had the same problem occur again, about 4 weeks ago, in Cheyenne,WY. If you did not get ceramic injector cups, you will more than likely have the same problem again.
