 Small Tygon flexible tube filled with oil.  No holes in housing.  On the SS part that screws into the side of the housing, I have a 1/4" tubing with Swagelok compression fitting.  I will connect to this port.

Cliff,how are you compensating for oil expansion due to heat with the KISS method.Are you just drilling holes in the housing & using tube?Alan

Actually in the spirit of KISS, I am going to start out using oil pressure compensation.  If I run into any issues, I will look at using the air or this hybrid of oil and air with a regulator.

Jon,the alternative is to follow Hugh's idea that Cliff is using & I am going to test out,& put a regulator in the system that is set it to around 4psi internal overpressure. This means you can fill with oil & not worry about getting everylast drop going in, or drilling the housing. You will also be able to run it air compensated. There is the safety feature that if you leak oil there is plenty of air to replace it.Cliff already has the parts sorted, just put your order in:)Alan

How important is it to get every last air bubble out?  Surely a fraction 
of the total volume is not going to result in catastrophic failure of 
the motor housing, is it?
