7875 + 5.9 + E85 + Megasquirt

Ok. Seems like with it being near the bottom of the pan it would push oil up directly into the can if pressurized. Maybe I'm seeing the pan connection wrong.
The bung is at the top of the pan in the front, well above the oil level. This is a rear sump pan also so under WOT conditions the oil should be mostly in the back and in the sump, far away from this bung. I still need to test some more but so far it seems to be working. Fingers crossed.
