Oil Pressure Sending Unit Adapter?
Tried to install a VDO oil pressure sending unit into the one Mazda uses for its sending unit. It barely threaded in 1/8 inch under torque.
The Mazda one starts off much more narrow but fits into a 1/8 pipe very well.
The 1/8 pipe starts off about 1/32-1/16" thicker.
How have others installed American sending units into the Mazda block.
This is for a friend I am helping.

finding the adaptor is the more difficult part , I believe that some auto-parts stores sell a kit for it .

If memory serves the stock hole is 1/8" NPT, I know Mazda used BSPT (metric pipe thread) on the FC which was strange.
But, I've seen "big" 1/8" NPT and "small", even taps that were different sizes.
Might just be worth installing it in one of those oil filter pedastal adapter blocks. Or, one trick I saw ages ago - take the banjo bolt for the rear oil cooler line and drill/tap it for 1/8" NPT, makes for a clean install.

maxpesce did an install using the stock location way back when. Here's the update he provided in his thread:

I just tried using my 1/8 pipe thread tap to recut the female threads in the Mazda adapter.
This worked and allowed the VDO unit to screw in about 1/4".
Thanks.
