I have a Smiths
oil temp gauge that has a wire-wrapped tube from the
oil pan to the guage. While attempting to fix a minor leak at the fitting where the line goes into the pan, I managed to render the guage inoperable. It now reads zero continuously. The tube does not leak and has no visible external damage.
The questions I have are:
Can this tube/line be repaired, and if so how?
If not, can the tube be replaced or must the entire gauge/tube assembly be replaced?
How does this gauge work anyway. I assume the tube is filled with some kind of fluid?
