Hi I am hoping someone who has fitted these gauges can help me out.

I am planning on fitting them myself next week, and have spent a whole day trolling through old threads.

I do know the bung in the engine under the intercooler is M18x1.5.
I also know the thread under alternator for temp is 1/8 BSP.

What I don't know is the size of the defi sensors, I have seen different sizes the more I search the more my head spins!!!

I have read the oil pressure and temp sensors are 1/8 NPT but on the defi site below it says 1/8 PT and you will need to order additional parts for 1/8 NPT.

-Will an 1/8 PT male fit into an 1/8 NPT female? (it doesn't look like it from that link)

-Will I need an adapter from 1/8 BSP to 1/8 PT

-Also if I just leave the original pressure sensor unplugged will I get a low oil light warning on the dash?

Can anyone who has fitted these gauges help me out please?

 

I fitted mine with no problems, am not sure of the size of the adaptors but i got the info off here and everything fitted ok.

And there's no problem disconnecting the original oil pressure sensor.

 

PM me with your email address and il send you my fitting insructions..
