Oil Pressure Sensor Under Filter Plate

I am trying to add an oil pressure sensor in the in place of the right side allen-keyed plug under the oil filter plate. I found the info and have purchased a 1/2" male NPT to 1/8" female NPT adapter/bushing. I first tried to thread the adapter/sensor combination as a unit but was blocked by filter drain spout. I then tried to put just the adapter in but cannot tell if I have sufficiently threaded the adapter into the port for lack of clearance for a wrench and I cannot tread the sensor into the adapter for lack of clearance from the filter drain spout. I have found a different adapter that does not have wrench contacts but I am concerned that if I have to remove the sensor it will remain in filter housing and then create problems reinstalling. Does anyone who has done this have suggestions for accomplishing this? Thanks in advance!

Edit: Pic not exact but closest I could find for illustration.

Never done anything like this, but I'm familiar with NPT, BSP, JIC, and more fittings. NPT threads are tapered so 1) I'm surprised to know that we had a potential fitting there and 2) I would put a sealant or thread tape to be sure not to leak. I just looked at mine and it looks like the drain nipple is a dissimilar metal from the oil filter plate. Maybe you can use the appropriate punch and remove that nipple. If you can't get a wrench on it, you may be able use a small pipe wrench. I was able to wiggle my pipe wrench between the plate and radiator hose, that is, after removing the fan shroud and fan.
