 Tracy should confirm this but I think you want your oil return to enter the pan above the oil level in the pan. Otherwise you risk oil backing up in the redrive. You also risk pressurizing the drive and possibly blowing a seal. I know in turbo installs this is true and a return line into the pan below oil level is a definite no-no.

 I plan to return oil to the cover plate where the oil metering pump used to be. I think this is where Tracy returns oil as well.

Now that I ve discovered these fittings, I ll probably return the redrive oil directly to the pan, via a 14mm to AN6 fitting that I ll put in the drain plug hole.
