There are 2 bungs on my intake manifold for temperature sensors. I have a stock temp sensor for the ECU w 3/8 npt in one and it works good.

I would like to install another sensor in just for the stock temp gage on dash but it needs to be 3/8 npt to screw in properly and also work w stock gage on dash. Any recommendation on which sensor is in range w stock gage w 3/8 npt is appreciated.Thought about making/buying adapter from npt to metric but figure one of you had to have figure this one out already.
I have a couple of stock sensors for the temp gage but threads are metric (not on npt)

Thank you
Dra

All pipe fittings on SQs and BSPT (British Standard Pipe Taper).  You can find adapters online.

Thank you for the response.I am using Chad's velocity stack intake.Sender for the stock gage is what l am after  stock is M16 x1.5   my manifold has 3/8 npt hole  l would like to avoid using the adapter and shooting for sender w 3/8 npt that will screw right in and work w the stock gage. Possible aftermarket  one.

Even the aftermarket stock sensors donít usually work.  They typically arenít calibrated the same.  I just recently pulled out my new aftermarket sensor because it was reading 3/4 at ~180 degrees. I tossed in a 30 year old original sensor and it works fine.  

Btw this gauge is not a tapered thread.  It is a metric flat faced o ring boss. M16-1.5 ifmemory serves me correctly.  Itís very similar in size to a 3/8 npt but I dont believe youíd be able to tap your tapered thread hole to the metric o ring boss
