I'm fitting some Defi gauges and have just found out I need some adapters for the sensors, here is what I've found out so far.

Oil Temp
Goes in a hole above #3 cylinder. It has a thread size of M18x1.5
Adapter is M18x1.5 -> 1/8NPT @ £3.70

Oil Pressure
Still abit lost on this one, I need a T-peice adaptor. The Defi sensor's size is 1/8PT but I can make it a 1/8NPT. I just need to know the size of the original pressure sensor now so I can order the right bit. I don't want to strip my alternator out to get this information though

So question now is - What is the thread size on the OEM pressure sensor?

 

Mickle the defi sensor goes straight in the hole where the oem sensor was
I tried a tee piece couldn't get it in kept fouling on alternator(too high) you don't need both.
ken

 

The thread size is 1/8 BSP so you will need a 1/8 BSP male to 1/8 NPT female....easy eh!
