Taylor Bulkhead Diesel Heaters safety?

The blue button thermocouple may be broke allowing constant drips. Buy a new one.

I think that one might be alright, it only drips when I press it. I just mentioned it because it didn't do that earlier. I do have 2 spares actually.

I do have some ptsfe tape, but I think I'll just get olives and new pipes.
