Now for the bad news: You can sorta see in the last two photo's that when I drilled the hole in the lid I slaughtered it. It's probably the worst hole I had ever drilled. For what ever reason the bit took out chunks of plastic in some parts of it, creating a very un-cirlce like hole. The o-ring on the inside covers the nicks in it, but the outside ring does not. The inside just isn't enough to create a good seal so I'm going to have to rework it somewhat to make a better seal. Also I don't like how far down into the container the pump now sits, so I may end up just scraping this lid and try out the other one and see if I can't do any better.
I noticed something as I was posting these pictures that I'm going to have to check on. The first pic of the new finished intake there is what appears to be a crack in the container. I didn't notice this before now. I'm hopeing that it's just a scratch on the plastic and not a crack. I didn't find it leaking from anywhere along the bottom when I tested it.
I belive that I'm also going to get some more threaded/barbed fittings and remake the intake and return hardware that sits in the tank.
