On a new van (to us) we have these clip on gauges.
Can anyone comment on how accurate they are as on the active cylinder it stayed at the top for a long time, then suddenly was in the yellow and now red. Yet there is still gas coming out. Getting it out to weigh is difficult.
So many options of what could be wrong and we have already changed the gauge to a new one which is still red.
Could it be that they indicate full until the last dregs, or maybe the rod/magnet in the cylinder has failed, or maybe we have a gas leak.
Any thoughts?
