Freeze plug size for back of water pump (using Elec WP).
I have a WP housing with the guts removed already. It appears that it needs a freeze plug in the back...but what size?
I tried searching, nothing helpful. This will be my first Elec WP install...
Or, maybe you'd have luck calling up CSI and/or Meziere and just ask them. Tell them you didn't receive a plug with your kit and you need the right size.
