K series - Mechanical oil pressure and temperature guage

Hi all

I've found the electrical oil pressure gauge on my 1992 1400 Supersport always to be somewhat erratic and currently seems to be all over the place and would guess the sender may be the problem. I know a lot of people recommend replacement with a mechanical gauge and although saw a "Caterham kit" on demon tweaks for a pressure gauge, I  also saw a dual oil pressure and temperature gauge per link above.

Does anyone have any experience of these - any good or a waste of time

How do you plumb in the temperature bit - through a T piece where the current electrical sender is and take both the pressure and temperature capillaries from there or a sump plug conversion for the temperature bit. Neither seems ideal - the former as I would guess this could affect the readings of one or both, the second due to the exposure of the sump worries me, with the potential for the capillary tube to be damaged/ sliced from objects being thrown up

Any thoughts welcome
