My 2003 Mustang GT has an oil leak

Ok I have an oil leak. I have located it but don't know if I can stop it or if I have to replace the part. It's leakin from where the oil filter is mounted on. Not from the oil filter but there a the part it connects to there a piece that goes straight down and a screw is in there and it is leaking. I don't know what that peace is called. If you all have any suggestions they are welcome. Thanks.

Are you referring to the oil pressure switch? That is located right next to the filter with an electrical connector coming off of it.

I had the same thing happen to my 02 GT, what I di was when I changed my oil, I removed that allen screw put some RTV sealant on the screw and put it back in. I let it dry overnight, then put on the filter and added oil and never have had a problem since
