Fixing the Evo Oil system - External Oil Pressure Regulator. Why and how?
Thanks for that. So if the stock oil return hole is unplugged, does oil continue to return to the back of the pan in the stock location as well as via the new front of pan return system?
Also I asked this elsewhere but I'll put it here to consolidate - the pans stocked by Benny at Benchmark all have additional NPT ports next to the oil drains. I don't need this, I have an oil temp/pressure sensor in the housing already. Are the pans available without these additional ports?

No, all pans come with the 1/8NPT ports and they come with a bung if you dont want to use them.
