oil pressure and water temp gauge

Anyone know a good make that fits the 2.5N/A plus capillary tube(s)?

Or failing that do you know the thread size for the oil pressure switch and water temp sender for a t piece to go in?

I dont trust the standard sender in my series 3 and feel its worth having an oil pressure gauge for a general health of the engine

Not sure but I think it's m10

It is on the 200tdi deffo but I don't know if it was and imperial thread on the na,

id go for an electric pressure guage rather than capillary with a t piece too so you have both

Or have a look at Vehicle Wiring Products website, they have a electric Durite guage which comes with a sender.

Thanks will definitely look at an electric one now.

Thanks zeaphod, used them a few times during my series project, dont know why i didnt look there sooner haha
