I wanted to fit a dual water temp/oil pressure (both mechanical) gauge in place of the original water temp instrument.
Knowing that the car likely would have oil pressure in the region of 50psi, I didn't want a gauge with 0 -100 psi, as pyschologically, I would feel better with a needle sitting past half way rather than under or on it. I also wanted 0 - 110C, mainly because my head works in Centigrade, not Fahrenheit, and I also didn't want the C-N-H version.
I found a 0 -60psi and 0 - 110C guage (nominally a Lotus item) at Holdens, everyone else had 100psi versions.
The gauge came with an adaptor for the temperature capillary bulb that fitted into the same place as the existing electrical sender, and the capillary tubing was plenty long enough to route across the dash and out of a nice big existing hole where the wiper rack enters. The Stag dash has to be one of the simplest to take out!
Oil pressure fitment was with a standard t piece to retain the oil pressure warning light switch.
Fairly straightforward fitting, I now know the cars runs 50 - 55psi hot at 3000rpm, idle pressure is 35plus. I think they are reasonable figures for a TV8. Temperature wise (and I did check the calibration of the gauge in boiling water first!) she runs 85 to 90C on the move, creeps up to 95 stuck in traffic, when the electric fan (also newly fitted) cuts in and brings it back down.
With a break only to watch some beach volleyball (has to be done, eh chaps?) it was an enjoyable Sunday's tinkering.
Picture of the guage was taken after shutdown, so some heat soak is responsible for that reading!
Oh - for clarity, it was women's beach volleyball.

Just thought I'd point out the alternatives
