Oil Pressure / Temperature Gauge Retro Fit? 1988 1.9 Petrol

Hi all
My low oil pressure buzzer keeps going off seemingly haphazardly recently on my '88 1.8 petrol Autosleeper, so I'd like have that disabled and have it replaced with an oil pressure and oil temperature gauge - either two gauges, or all in one (if that even exists)?
I'm a bit confused with all the different types of gauges / senders etc. I'd have this fitted by my local T25 specialist, so I'm wondering if there is such a thing as a whole off the shelf kit that I can buy for this?
TIA :-)

Ah worry gauges. I’d fix the problem and leave it at that if I were you. Have you changed out the blue sender from under the push rod tubes?

I haven't investigated myself, I'll be taking it to a garage to get it fixed.

I don't really like (or trust) the buzzer system any more, so I'd rather have gauges so I can actually see what's going on :-)

Get the oil pressure tested at temperature first, there's no point spending money fitting gauges that tell you with more accuracy that you have a problem. The problem remains the same and you have done nothing to fix it.

Have a read here - half an hours work for a garage to do the test

In my case I was content to replace the warning switch with one of a different value,that might be all you need to do (especially if the switch is failing anyway)

Make sure you know what oil grade is in the engine too, if the age is unknown do an oil & filter change first. Choose between 15W40, 15W50 and 20W50

Thanks and yes good point to test the oil pressure before doing anything.
