I think I found my oil leak

Hi, new member here, and I'm glad to have found your forum. I just have a question about these parts in the picture I took yesterday. I'm hoping this is why I have oil dripping on my exhaust and all over the driveway when I park.

Is the long one that's perpendicular to the piece coming out of the block the oil pressure sending unit? If so, replacements look different than the existing. Also, the one with the wires visibly connected to the right, is that a fuel pump safety switch? I think I'd read something about that but not sure if it was an earlier c4.

It's a 1990, I think they changed things around on the 1990 model.

Thanks for any input.
