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!
