Brian, are you talking about the capillary tube between the sensor bulb and the temp gauge itself?
This has fascinated me for years as the weakest part of the whole thing is the soldered joint where the tube meets the sensor bulb which of course is where the most vibration occurs unless the tube is secured to something on the engine upstream from the bulb. I'll check the parts list when I get home but I cannot recall there is any standard part for this and I have seen hundreds of cars and photos (even Lotus ads, manuals, etc.) where there is no securing arrangement.

I made a clip from a brass strip and a piece of rubber - secured to the flange of the heater valve with a self tapping screw. See attached photo - not close up, but you can see the idea.
If you find there is a standard part or standard solution, let me know please.
Rgds,

Elliott thanks for the reply and photo.
This photo is taken from the S4 handbook showing the securing clip lotus recommend fitting.
John Bolster's excellent book, The Lotus Elan and Europa a Collectors Guide shows a under bonnet shot of a S3 page 34 with what looks like the same clip fitted
I have not yet found a part number and my S3 handbook as no reference to this part
I think like you I will make my owe

Per the conversation in this thread:

Here are a couple of pictures of what I assume is the "correct" clip, and a picture of the P clip that I used. There's a handy hole in the valve plate that allows the P clip to be bolted in place.

This looks a familiar issue.

After ALLOT of searching i decided to go with the same style of routing as the BRM Elan at Maul Mattys.

When i did mine i just drilled the Pop rivet out and refitted the rivet but with a Pipe clip added (just use bits of clear washer pipe between the clip and the Capillary so it grips it but not hard enough to cause damage, if you just use a metal clip the Capillary moves about or rattles)

Not the best pictures as the loops are very even and straight its just the picture makes it look cock eyed.

This is the one i copied (just loved how neat it looked) mine is not as well installed but looks good enough for me
