Where the oil pressure switch screws in on the c20let can anyone tell me the size of the hole and the thread type.
I want to put a t-piece in there to allow me to run a gauge off it.

cheers

matt, why not buy a vauxhall oil pressure switch and sender unit, available from autovaux for approx 35-40 quid?

Didn't know you could actually. I suppose thats the setup they used on the the calibra?
Will that sender unit work correctly with a non vaux gauge.In my case revotec gauge?

And the normal T peice you get from Demon Tweaks and others (M14x1.5 and 1/8 NPT) is too long with the standard pressure switch in it and fouls on the TXB mounting bracket.
Does anyone know any others that do M14x1.5 1/8 NPT (or BSP) T pieces that are shorter? Had to block off the standard switch connection and only run the gauge on mine.

I think I used a random collection of copper washers and brute force to make mine point up. Though found out at the weekend it is a bit in the way of the turbo oil feed connection.
