I'll be starting my engine for the first time pretty soon.  I was wondering if is necessary to do anything to get the air out of the hoses that carry fuel and oil to the fuel and oil pressure transducers.

Tom, I don't know if it's necessary, but before starting a new engine or
one that's sat for a few years I pull the plugs at the nose end of the
oil gallery and pump oil in there. Next I pull one plug from each
cylinder and crank for 15 seconds, wait 30 seconds and crank for 15 secs
... until I get oil pressure.

Crack the fitting on the carb and run the aux pump until you get fuel.

Set everything for start and have at it.

Now, if you're just worried about air in the sensor lines ..... don't.
The air will make the reading 'spongy', but in short order .... pressure
is pressure. Depending on where you have the fuel pressure sensor
hooked up, the air will dampen pulses from the mechanical pump that will
destroy sensors or gauges over time.
