SUBJECT:
CONNECTING PRESSURE SENSING DEVICES TO OIL GALLERIES
Oil pressure sensing devices, such as senders and switches, must
never be connected directly to any oil gallery of an engine.
The reason
is simply that continued engine vibration causes fatigue of the fittings
used to make such a connection.
If these fittings fail, the engine
loses its oil pressure and very quickly siezes.
Such pressure sensing devices must be bulkhead mounted and connected
to the oil gallery using an appropriate grade of lubricating oil hose.
Any fittings used to connect the hose to the gallery must be of steel or
malleable iron.
Brass must not be used for this purpose.
