Need a source for the 1/8" BSPT to 1/8" NPT adapter for an oil pressure hose coming off the block. Found a 1/8 BSP male to 1/8 NPT male adapter at Pegasus, is that the correct fitting?

First things first:
"G: Series British Standard Pipe - Parallel ( Straight ) BSP or BSPF
Also referred to as British Gas, British Pipe Parallel or Parallel Fastening thread.
Various Symbols: BSP, BSPP, BSSPI, BSPF, BSPG, PS, R, G.
"Rc: Series British Standard Pipe - Taper- BSPT
Also referred to as British Standard Taper Pipe or Pipe Taper, or Conical Thread.
Taper is 3/4" taper per foot ( 1 in 16 on the diameter)
Various Symbols: BSPT, BSPTr, PT, KR, Rc.
Per your posted comment, you require a 1/8" BSPT to 1/8" NPT adaptor. Is that 1/8" BSPT male to 1/8" NPT female adaptor? Referencing the included info, no, BSPT is a tapered thread and BSP is a straight thread. We all understand NPT is a tapered thread.
BSPT Connections. BSPT (British Standard Pipe Thread) is similar to NPT except for one important difference. The angle across the flanks of threads (if you sliced the fitting in half long-ways and measured the angle from root to crest to root) is 55 degrees instead of 60 degrees as it is for NPT.
BSPT equivalent is NPT and BSPP's equivalent is NPS. Never swap threads if it is a high pressure application. NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most sizes have a different pitch.
In short, JAMING two different threads together is looking for trouble.

it's not clear what you're trying to do.
If you want to put a 1/8" NPT male into the block, this will work:
Auto Meter 2269 1/8" NPT to 1/8" BSPT Oil Pressure Metric Adapter

Leftover engineering policies from the days of being under British influence?
Mazda got a great deal on the oil pressure senders when they were designing the engine-only to find out they were BSPT?
If this is for a gauge sender line, just use the BSPT to AN4 adapter and be done?
I have the fitting and the complete kit on the shelf. I buy this fitting in bulk for my oil sender relocation kits.

That's a pretty long way around to saying "no", or the more wordy version, "no...it turns out BSP is actually different than BSPT". Or the even more wordy version made by adding on "...if you want to know the gory details of all the various thread standards, see the following link: https://en.wikipedia...h_Standard_Pipe."
Further, he never said he wanted to "jam two different threads together". He simply asked if he'd stumbled upon the right thing.

I didn't lose, I just got outspent!
Tom, jamming threads was a per say a warning comment, don't do it. The remainder of the details of threads was a teaching moment. Nothing more, nothing less.
