Remember, simple is NOT the same as easy.
The "fluid", in the bulb, that your are working with/against, is
ether. Highly volatile and flammable.
Dry ice is the key component, freezing the bulb, of the new gauge,
while prepping everything is a big key to the success of the
project, as is making the splice a good distance away from the back
of the original gauge back. It's quite easy to un-solder some of the
If you have more questions, before attempting this, e-mail me and
I'll try to answer them. I've done this several times.

One can repair these By purchase a replacement gage,
Freeze the “blub” (the part that screws in block) so the
fluid will not leak out. Cut the old “bulb” off leaving
enough tube to solder new bulb cut the new froze bulb.
With a peace of 1/8 inch ID. tube spice the new bulb to
the original tube then solder.
Note: You may want to make the spice so it will be
under the dash out of site.
Install new blub and gage in freezer Do not
cut until you are ready to spice the two together.
Dry Ice is best if one can fine it.

block thread is 5/8" X 18 (as I recall) fine thread.
The chances of the tube being just kinked and not working,
are slim. If it's not working, most likely punctured and
leaked the fluid out.

I'm looking for a little help and
advice on the engine temp sensor. I accidently bumped
the capillary tube while replacing the battery on my Hot
Shot and now the gauge doesn't work. The end that goes
into the block appears to be undamaged but there must be
a bad spot on the tube. If I could locate the damage on
the tube is there any hope in straightening it enough to
make the gauge work again? If not, I have a couple other
questions to clarify things:
Thanks for your help.
- Does anyone know the correct thread size where the
bulb goes into the block? I bought a brass plug with
3/8" pipe thread but it appears to be a hair too
big. I'd like to plug the hole so I can drive the
car a little while waiting to get the gauge
- Does the backing plate that holds the gauge into
the gauge cluster on the dash have to be removed
along with the gauge? I took one out about 20 years
ago to get it fixed but don't remember this issue.
- Does anyone have a recommended place to get the
gauge repaired now that Bob Potts is no longer doing
