Yea now that you mention it. It doesn't make sense that that part would be pressurized. I'll check the piston rings first and go from there. Thanks!

I tore everything down this afternoon but left the motor assembly alone. Piston rings are fine. Nothing else looked worn or out of place either. So I cleaned everything and put it back together. Still leaks around the power cord for some reason but it's now making enough pressure to actuate the lockers. It's still not holding enough pressure to fill it's tank and be able to stop pumping. I guess I'll call it a partial victory for the time being. I think I'm going to buy a new one in the near future. I kinda like that twin compressor ARB is making now.
