Sealing oil sender connection

Looking under the hood the other day I noticed that where the connection for the oil pressure line attaches to the block is leaking. this is just a brass fitting that screws into the hole where the oil pressure sending unit used to screw in. I switched some years back to a manual gauge. What type of sealant do you put around the threads to stop the leak? I'm assuming that standard plumbers tape would be eaten away by the oil.

Yes, it is a mechanical guage with the tube and compression fitting. I think the compression fitting is okay. It "appears" that it is leaking from the threads that screw into the block, but I am not positive. My first move is to try the teflon tape route as it is the easiest. If it leaks after that I will replace the compression fitting. I'm hoping the tape will fix it as I don't want to try to find the correct size compression fitting. I remember it as being very small........
