Mounting:
The gauge requires an oval cut out that as shown below. It should be
inserted into the opening from the front and the U-clamp will be installed from the
back. Tighten the two nuts on the U-clamp so that the gauge is secure. Figure 2
shows the required cut out for the gauge. Figure 3 shows how the gauge
mounts.
