Oil Pressure Sender adapter solution!
OK, so I am sharing this with all the generations on this forum.
I search here and there and everywhere trying to find a solution to this problem and found only 2 options, but not this one.
While installing my Autometer Oil Pressure sending unit today, I found 2 problems.
1) The sending unit is too close and interferes with the block,
2) The thread pitch is 1/8 NPT, and the block is 1?8 BSPT
The two options I found were this:
1) Try to get it started then just torque it in (fubaring the threads for any other use)
2) Get an adapter that is 1/8 NPT female and 1/8 BSPT male
The only problem really is that the adapter is about $9.00 and has to be shipped (good luck finding it locally) and the "ram it home" solution is destined for problems.
Here is the simplest solution, and I don't know why I haven't seen it before.
Cut the shank with the threads and the hex section from the old sending unit. Drill and tap that shank for 1/8 NPT. Now not only do you have the required distance from the block to clear, but you also basically have the adapter already there to use.
Note this is only for those of us using the stock sender location.
Many thanks to David Grafinkle. He knew exactly what to do when I asked him for a resolution. He said that is something they used to do years ago when there were no adapters.

That brass stand-off is already a separate piece on some cars. I used the separate stand-off that was on my car when I replaced the stock oil pressure sender with my SPA gauge sender.
