Insert the needle into the buffer tube assembly and fill it with oil to the
top of the set screw
When extracting the needle, continue to apply pressure to the plunger
to maintain the oil level

Ideally, the meniscus at the air-oil interface should be convex to
minimise the air in the final assembly.
Do not apply pressure to the plunger when the syringe is installed
on the pressure port! Doing so may exceed the pressure rating of
the sensor.
