I installed a Autometer electric oil pressure gauge #3327 in my 04' 2.7, last thing I need to do in install the sensor. I wanted to mount it in the same hole (eng. block) as the stock switch (doing away with the idiot light), The first thing I encountered was the angle of the hole and the size of the Autometer sensor hitting a bracket for the A/C compressor. I picked up a 45 deg. 1/8 NPT (thinking that is the size) to change the angle so the sensor would clear the A/C bracket. Now I find out the 1/8 NPT doesn't screw in. I looked on-line for any reference to this matter and came up with nothing, looked at Autometers site and found "Metric Adapters" #2269 1/8" NPT to 1/8" BSPT or #2265 1/8" to M10x1 (I don't think the hole is 10M). At this time , I'm hair less now, any help from the experienced would be greatly appreciated.
