Dry sump problems.
If anything.
It seems like the oil pump is sending air backwards to the bottom of the tank.
Lines are not backwards. Checked them upwards of 10-15 times. I have videos proving all troubleshooting.
But cannot upload them here. I’d be happy to talk to people personally through email so I can send videos. Or give me an easy way to post 5+ 1 minutes videos somewhere.

in the video when the oil goes down inside the tank. That’s because I ran the primer.
and if I keep the pump going the gauge will go to 0.
In my video with the top hose off the tank going into the pan in the trunk. You can still hear the tank bubbling from the bottom hose.
The last video is me breaking open the oil pump inlet from bottom of the tank. And draining the tank from it.

Just watched the video. Saw you using a drill but only forwards. Almost certain you have the hoses backwards on the pressure pump.
I also didn't see any oil returning to the tank in the video. You should make sure the scavenge pumps are primed and working by pouring a quart to two of oil in the engine and running the pumps with the drill to pump it back to the tank.
Maybe the whole pump is installed up side down?

Btw the primer isnt going to do what you think it is. The problem with a dry sump is the oil drains out of the tank when the engine is off. When you start the engine there isn't much oil in the tank to feed the pressure pump long enough to give the scavenge pumps enough time to refill the tank so the motor oil starves for a bit. Using a primer like you have now is going to make it worse by sucking even more oil out of the tank before start up.
You need to drive the scavenge side of the system to fill the tank before starting. That usually means pulling the belt off.

pump is not upside down.
Next contestant please.
and the primer will Work exactly how I think it will.
And my previous loop in my feed line kept the tank from draining into the motor while vehicle is off.

It looks like we have a pissing match. Which is all well and good, but we still have a fellow Evo'er with an issue. So, if we could put the fun aside for a moment we might be able to still help him out.
