Hi=20 Wendell,

Sorry if I'm=20 the one that steered you wrong on this. I have a note = that M10x1.0=20 fits, and I'm sure it did fit the ones I've tried. There=20 was at least one other case where one of my noted sized = didn't fit=20 someone else's housing, so it's possible they do change from one year = to the=20 next.

Just to be=20 sure, are you talking about the actual threaded hole in the rear=20 housing? Seems I recall that the stock arrangement used = a straight=20 fitting that extended out from the housing to the sender. If I'm = remembering that correctly, then the sender could be different from = the=20 threaded hole in the housing.

Good=20 luck,

Rusty, I'll = let you take=20 the blame.

The oil = pressure sending=20 unit on my '87 13B appears to be 10x something. The adapter = diameter is=20 right but threads are too course on the purchased adapter. Barry = mentions a 1/8 BSPT which I have never heard of (haven't heard of a = lot of=20 things). I went to JC Whitney site and they show a 1/8x28 BSP = adapter.=20 Barry,is this what you're referring to?

The port = for the temp=20 sensor just forward of the oil pressure sensor port on my engine is = smaller=20 than the oil pressure port and I have no idea what it is, but am = going to=20 use the original temp sending unit case, drilled out to accept my = solid=20 state sensor in this location.

It might be = better to get=20 an original Mazda oil pressure sending unit (original one seeps oil) = to fill=20 the hole and use a gauge that will be compatible with it and get oil = for the=20 re-drive from some other source. Does anyone know if the Mazda = sending=20 unit is compatible with after market gauges?

Could = try getting=20 kit from JCW and see if any will work. Already wasted more on the one = from=20 ACS.
