Oil pressure sender questions

My mechanic buddy diagosed why the oil pressure light does not come on on my '52 Packard 200 with 288 engine, when the ignition is turned on. He said I need a new oil pressure sender, so I ordered one and it is in.

The service manual is silent on how to install it properly, and the torque specifications charts do not cover it either.

So, 3 questions:

1. What torque should it be torqued to? (I do have a torque wrench)

2. Are you supposed to use that white sealing tape on the thread? I ask because I assume this sender needs a ground connection (there appears to be only one wire to it), and wonder how it gets a good one if you use sealing tape.

3. If the engine is "off" (i.e. oil unpressurized),and cold, will you still get any oil leakage when you pull out the old switch?
