Low oil pressure makes me nervous

I installed the (new and "improved") oil pressure sending unit in place of the existing one (original?) I mentioned in Post #74 above (there was no sealer on the threads so I used teflon tape).

The factory gauge is now reading double (twice as high) during both cold and warm engine operating conditions, compared to what it displayed with the old sending unit. I'm going to relax now, and discontinue checking the oil pressure every 15 seconds like I have been. I still plan to slip a mechanical gauge in there somewhere.
