REFLECTOR:Sensor Mounting

[Brian Michalk]

It depends on the sensor.
Most of us seem to use the VDO sensors that I have heard are prone to
cracking.  The good thing is that the pressure orifice is very small.

There are plenty of industrial sensors that will withstand our engine
vibration, but you can't buy them for $35 either.
