Sorry, didn’t get an email about the posts regarding Demon Tweeks. I phoned them up to place my order and used the standard Smiths part number to quote. It isn’t on their website.
The contact there is Dave Kimberley, davek@demon-tweeks.co.uk and the part was ordered in from Smiths before being posted on to me.
Hope this helps.

Nice one Dalamar
I suspect when DT said they went to Smiths they're referring to Caerbont who supply the TT6811-03 sender and many products branded as Smiths.

So it looks Caerbont either let DT order the TT6811-03 in singles or DT ordered two or more, in either case DT are definitely worth a call for anyone who just wants one TT6811-03 sender.
Nice work Dalamar, it looks like you've sorted it

Got my sender before my holiday, now it is installed (just by removing the ecu sender)
Also lost some coolant (very little).
Fired up the V8, no leaks, running as sweet as normal.
Temp is rising faster than normal (with TVR sender) it is also reacting faster on changes.
I always had the feeling the temp gauge was lagging, so in traffic it raised quite slow, and afterwards in free air it came slowly down.
Now it reacts way faster as in my opinion it should.
+1 for this hack :-)

That looks spot on Dalamar The only downside to this TT6811-03 sender was Caerbont's minimum order quantity of two, so at just £14.18 delivered it's a no-brainer for people to go to Demon Tweeks now & buy it singularly.
Great work and thanks for sharing

Nil stock 14 days to order in.
Damn.

I’ve just caught up with this and installed one of theses sensors myself.
Demon Tweeks told me to expect delivery in 4-6 weeks, but actually it arrived in a week or so.
Access is a bit awkward, but I found it easy to get a 12mm ring spanner on once I’d disconnected the HT leads, removed the distributor cap and removed the ECU sensor (19mm spanner). This creates plenty of space to go in with a spanner from the front.. I lost about a dessert spoonful of coolant. The new sensor needs a 13mm spanner.
After initially not firing up, I decided to fit the HT leads to the correct positions. I had them in the right order, but they were all moved round by one position. Oops.
The indicated temperature came up far more rapidly, and reached an indicated 100°C before the fans kicked in. On the road, the indicated temperature is locked to about 91-92°C. When stopped, the temperature rises rapidly to nearly 100°C before the fans kick in and it slowly returns to about 91-92°C.
With Rovergauge connected, I found that the new sensor consistently over-reads by about 3-4°C, but it parallels Rovergauge quite closely. So the fans kick in at an indicated 98-99°C, with Rovergauge showing 95°C. On the move, the gauge is showing 91-92°C with Rovergauge reading around 87-90°C.
I haven’t yet done a long motorway cruise on a chilly day, which will be the acid test. The TVR sensor usually shows a cool 80°C or so, probably because it is influenced by the cooling airflow that chills the stagnant water that it’s sitting in.
So I will need to get used to seeing the indicated temperature go up to nearly 100°C when stationary, but I can see the effect of the fans much more directly now.

It seems some of these sensors are accurate, some not. The one I fitted a couple of months ago reads about 5C less than rover gauge indicates, not much difference to the original TVR sensor. Looks like yours is inaccurate in the opposite direction.
Could be some gauges are more accurate than others too!

They do take a bit of getting used to. I had an early start a few weeks ago and happened to look at the gauge after a few miles and it was up at 95deg, as I watched it went back down 65 deg then after a while back up again to 95deg. The next drop it settled at 80deg. Obviously as the thermostat was opening and closing. Normally this time of year I would be lucky to see 50/60deg.
