I just wanted to follow-up and thank all of you for the invaluable advice.

I ended up removing / replacing the screws, removing the crooked gasket and replacing it with butyl tape, sealing around the edges and adding some weather stripping around the inside of the cap.

After a few heavy rainstorms the last few days I'm pleased to say that water's no longer getting inside of the power inlet.

Thanks again!
