Pry out the old one before you screw in the new tube. This way, you can ensure by looking into the hole that the tube is not too deep. Then simply tap in the new welch (freeze) plug. Order a 3/8" tube, even if your cap has the older 5/16" tube. You'll need to re-tap the threads in the cap for this larger tube. JB Weld or braze the new tube in place. By installing the 3/8" drain tube, you will help the rear main drain oil back into the pan better. Ford changed from 5/16" to 3/8" in 1930 because of rear main leakage complaints.

Thanks you for that. That is one thing I was aware of as I have been researching this for a few days and read about not screwing the tube in all the way and why. I appreciate you mentioning it as it is pretty obvious that I am new to these engines.
