I need to send my temp gauge to Max Merritt for rebuild but have no idea how to remove the tube from the back of the gauge. I can remove the entire assembly, but Fred Bruner at Max Merritt said they just needed the gauge. They replace the bulb and tube along with rebuilding the gauge.
Does anyone have instructions on how to remove this tube from the temp gauge? If not, I'll just send Fred the entire assembly and have their tech worry about it.
Thanks, as always.

The bulb, tube and gauge is a single assembly with the tube being soldered to the bulb and gauge. The gauge is usually mounted on a backing or mounting plate which may also hold another gauge and that plate is what is screwed to the instrument cluster. There is typically a fairly large but thin nut and possibly a screw holding the gauge to the plate. By removing the nut and sliding it over the tube and off plus removing any other screws holding the gauge the long tube and bulb can be pulled thru the hole in the plate to free just the temp gauge from the backing plate. I would go with your second thought and send the gauge with tube and bulb still attached.

Thanks and I shall definitely do that. As I said before, I'm afraid of damaging the gauge perenantly. I did see the screws on the back of the plate and was able to remove the gauge from the instrument cluster without hurting it.
Thanks for your input and yes, I'll go with your suggestion.
