Return line plumbing help

[LEOreefer]

hello all I need some help with my return plumbing. I'm setting up a sca 50 with shadow overflow. It will be a herbie style overflow with a 1/2" pre drilled return line next to it. Below are pic of the bulk head I just got from BRS. I'm not sure how or what I would use to plumb this to my return pump? Any pics and suggestions would be greatly appreciated. Also what side does the rubber seal go on ?

I bought the same type of bulkhead from BRS. Very heavy duty item. I like it. The rubber washer goes inside the tank.

Here's a picture of the tank from the back. You can see the return bulkhead and connections in the upper left.

The gasket goes on the flange side of the fitting. Whether or not the flange is in the tank depends upon your plumbing setup, though I'd wager that the vast majority are set up with the flange in the tank.

Also, I've never gotten a strange look from the folks at Lowe's/HD when I'm test fitting parts.

Great thank you all. I will bring the fitting to the store tomorrow and fit it. Also how in the world do you get loc line apart ?
