Where to get a Stainless 3/8" sending unit?

I am running a stainless 3/8" line from my tank to my pump. The sending unit I have in my new tank didn't last two years (It came from Paddock before they closed up).

So, I am looking for a new 3/8" sending unit for a '74 Duster. I would prefer it to be stainless but... It doesn't have to be.

Does anyone have any recommendations who to get one from?

As you requested. $54.95
