Oil Temp gauge / sender Options

[Montreal914]

I've been seeing a temperature mismatch of about 20 degrees between my temp gauge and an actual thermocouple reading through the dipstick tube. Seems like the 911 temp gauge/sender mismatch is pretty common from what I've been reading. I've been using the standard 914 sender.

My gauge is a combination of various elements and therefore the actual whole gauge number cannot be used as a reference. Am I to understand that the temperature module was built in November 1980 as per the picture below? (IMG:style_emoticons/default/confused24.gif)





I found this chart either here or Pelican.



If my temp gauge was build in late 80, then I need to get a 911 606 112 sender.



Will this fit in the standard taco plate or is it too long?

I've been seing a lot of comments about late temp gauges being numberless which makes me wonder if I actually do have a 1980-81 gauge...

Is that date stamp to indicate when it was made or model year ? the number on the very outside of the gauge face will confirm,I was sold a tach and it wasn't as advertised turned out to be a 86 from a 3.2.
The 3.2 tach uses a different signal than the earlier ones but my tachadapt will cover that.
I have the same combo gauge and it is matched with a 150 degrees celsuis sender,I matched a new 50mm VDO to it and got close reading between the two,there is a VDO sender that you can cut to length but think it is only 1/8''npt ,I just used a reducer bush,not sure if you could use it on a T4 motor.
Is it possible the one you showed in the pic will be too long (IMG:style_emoticons/default/confused24.gif) .
