Ok, I will give it a try.

Does anyone know where I can get the part? I checked all the online sites of local shops, napa, advance auto, etc, and no one is listing 1/8 npt parts that look the same as the pictures.

I'd rather try and get it local, than order online.

If I cannot find one local, where do I find it online?

Also, should I use some sorts of thread sealant when installing it?
