ETS UICP and SD IAT sensor
Just tried installing my GM IAT sensor in my bung that came welded on my ETS UICP for my SD conversion and does not seem to go in far. Maybe 2-3 threads max. Is this normal? Is the sensor far enough down that it will be able to get an accurate reading?

So after talking with my tuner it seems that the bung may have been welded on backwards as he thinks that they taper down on one end and that is supposed to be on the pipe side so you can get a good seal. Or the other option they could of used a straight through bung like for an o2 sensor causing the tight fit. Maybe an ETS rep could chime in! Are the GM IAT sensors not compatible with your bungs or perhaps was a mistake made?
Question is will it work with just those few threads in? I was going to get tuned on SD tomorrow but I am not sure if I should attempt it with the sensor not all the way in. Anyone running SD have any input or run into the similar problem?
Any input is appreciated! Thanks everyone!

It is very possible it was welded on backwards.
I would buy a 1/4" NPT tap and keep going in until you can capture 3-4 of the threads on the sensor, in the bung. It really doesn't take much to seal and hold a brass fitting in, especially when it will only see 35psi max. Use a little teflon tape for extra assurance, though.

Make sure you clean that uicp after tapping.
Honestly, let ETS handle it. They're a stand up company. If they made a mistake not only should they fix it, they will fix it.

I'm wondering if the pipe may have passed through with some powder coat in the threads. If this happens the pipe fitting would become a lot tighter. The threads may need to be cleaned up. Also, do not put Teflon tape on the threads. This is a pipe fitting so the more you screw it down the tighter it gets.
I'm going to send you a PM.
Thanks!

As Robert said, pipe thread will generally engage less than half the threads, which is fine. It doesn't need to be cranked down on to stay in place. If you're worried about stripping it (and/or it leaks), just use some thread sealer (NOT Teflon tape) and it will be good to go. You can also get a pipe tap and run it in a little deeper so the sensor threads in more. But the thread sealer is a lot cheaper...
