Wow! I think I really missed the mark on my earlier response.
Your response seems to make more sense. That is IF the repop sending unit is working properly.
I have heard the repop gauges are not worth spit so if it were my car to diagnose, I'd surely make certain that is working before attempting to adjust the glass tube.
Plus, it (glass tube) would have to be WAY off for the gauge to read all the way below the low mark. I don't see where that would be possible.
