Apparently some gauges work better than others. We had one on a previous
grill. It was part of the connector coming from the grill, not a screw-
between device. It also proved to be pretty accurate. As the needle moved
neared the empty zone, a fillup proved that the tank was indeed nearly empty.
Unfortunately, I do not recall the brand.
