Land Rover 90 Temp sender question???

Can anyone help me.
I have just removed the horrible oil burner (2.5 NA) from my 90 and replaced it with a 3.5EFi Auto V8. My only problem I am now left with is that I have
used the original Range Rover temperature sender on the V8 and the Original temp gauge on the dashboard however as soon as the engine is running the temperature gauge moves up to 3/4 very quickly then up in to the red over 2 to 3 minutes even though I have tested the thermostat and can feel that all the pipe work and radiator are still cold??????????
Which do I need to change to make it read correctly the sender or the gauge???

I've got exactly the same problem with my 101. I fitted a IIa electric temp gauge and a V8 electric temp sendor.
I checked the temp on the run to Gaydon and at 50 mph ( I'm running low ratio standard issue Ambi transfer gears!) I was cooking at 85 degrees going to 87 degrees on long inclines as measured by a Maplins temp sensor in the top hose which I later managed to kill (the sensor is Only rated to 40 degrees C ). So I'm happy I'm not running hot it's a calibration issue.
Someone suggested there is a red temp sender and a white one... I've got the white one nut no idea if there is any truth in the existance of a red one. I only ever found one part number and no reference to another type.
I've a variable Pot resistor in the garage but I've yet to try that as Were still pulling Morph to bits and striping him back to bare metal :-)
Keen to know how you go on.

I have just been doing some other research on the gauges and have found that they list a temp gauge for the;
(Automatic - 4000 cc - L/R - V8 - Petrol - EFi - 50 LE - 90")
Which is Part No. AMR5722
but it's over 35!!!!!!!!!!!!!!
I'll let you know how I get on!!!
Any other suggestions welcomed!!!

I had the same thing on a 90 which was 2.5 petrol changed to 3.5 Range Rover engine. Looking in the parts catalogue it lists the following:
For the gauge up to JA916603 part PRC7311 from JA916604 to KA928139 part AMR2070 from KA928140 part AMR2631
For the sender V8, PRC2506 and PRC4430 (hot climate)
For the sender 2.25 petrol PRC2505
For the sender 2.5 petrol and 2.5 diesel PRC2505 (up to April 1989) PRC6663 (from April 1989)
For the sender 200TDI PRC8593
Hope this helps Richard
