Well, someone got their spergers on and did some research so you don't have to, for the sake of the community
I have moved to a haltech from my MS, and saw that they are available from haltech, for 150USD including an M10 to NPT adapter and the connctor which is better, but let's just say that haltech are not the kings of bargain basement, so if you can get it for 150 bucks from them, it can be had cheaper.
So with that valuable info, we have more. Search that part number and amongst other things, we have an eBay listing https://www.ebay.com/itm/192948285779
From which we have a fitment table
And whaddaya know, of all things a MAZDA part number.
tadaa, 60.37 at priority, was something like 58 at Tasca, and that was as far as I looked. 40% of the suspects listed at the top, and a criminal 25% of the place in NY.
Calibration data and pinout is identical, and the 2nd link shares the PN with the mazda and haltech item.
THose guys also sell jsut adapter for the npt to m10 fitting. Or you can find them on ebay https://www.ebay.com/itm/Pipe-Fittin...P/202378002629 or I am sure mcmaster probably has them. Also htat place in oz delivers to the US, and with shipping if you were to buy just the sensor, connector with pins, an the adapter you would be looking at aboot 130USD to have the full shebang shipped to the USandA
Updated 101821 https://www.haltech.com/product/ht-0...-bspt-adaptor/ these were 12 bucks when i bought, them, now 17.
Bought from werner mazda these washers 9956-21-000 2006-2020 Mazda Brake Hose Gasket $1.98

the comment below is with regard to ebay spec knockoff sensors; relevant context regarding the bosch at the bottom of the quote - from head engineer at LINK
I know of at least one car locally that has caught fire due to the end blowing out of one of those sensors, luckily it was saved with minimal damage due to it happening on the dyno with plenty of extinguishers around, but it may not have been be so lucky if it happened on the road. So perhaps you arent considering the cost of a failed sensor - it may just leave you stranded due to it failing and giving say a false oil pressure limit. Sometimes when they fail they short the 5V rail so all sensors no longer work. Or it could be as serious as loosing the car or engine.
The second factor is the tolerance of vibration. I only really have experience with relatively harsh race engines so road car engines may be more forgiving, but most of the cheap sensors dont last very long if fitted direct to the engine - and I mean even the cheaper name brand ones such as honeywell px3. Theses all need to be mounted remotely which if you add the cost of decent hose and fittings each end you are probably near the cost of a good sensor that will tolerate direct fitting.
The only sensors I have have had little failures from when direct mounted:
Honeywell PX2.
Link/Variohm/Eurosensor
Bosch 0261230340 <this is my goto at the moment, decent price, temp sensor built in and have never had one fail. Unfortunately the connectors arent that nice.
So there ya go, that is what my afternoon was spent researching while on the clock, hopefully this is useful for someone who wants to minimise the number of sensors in their bay, and it turns out they are actually pretty affordable and durable. I have plans to put at least one in my shitbox for oil pressure and temp on the tee for turbo feed. I need to run a fuel pressure sensor and it appears that these are fuel safe as per bosch so even if I don;t wire the temp in, it could be a good alternative to a PX2, and the same for CLT and coolant pressure.
High 5 all!

I found out today that certain C70 volvos have dynamic headlight leveling, via two analog position sensors mounted to the control arms. They are analog output, but very clean no contact rotary encoders of some sort inside instead of resistive wipers. They automatically zero, have around 90 degrees of range, and they seem pretty quick. Volvo headlight level sensor in google will find them, pretty cheap.
Also, be careful with the cheap male to female converters. They can be paper thin around the middle.

Interesting! Might be a good substitute for the rotary switches haltech sells. And thanks for the heads up on the m-f converters. Unfortunately, looking a little more, the cup does not runneth over with options for the female 10mm to male npt. Many options going the other way, typically for installing aftermarket gauges but putting european sensors in 'merica spec holes is not the usual direction of travel.
I have been looking on those for quite a while. The only issue I see on an oil sensing application is that I cannot figure out a location where I can reliably measure pressure while having enough flow to reliably measure oil temp as well.

yep. Stagnation. The solution I thought of was on the tee for the turbo, but that doesn't help if NA. You can find various port setups but you need to tap off the block and return it for it to work. Efihardware.com has a few options, but there is no "attach to block here" option that I can see.
I believe a 1/8 NPT is too wide at it's largest to drill and retap to M10 unfortunately. It might work, but the threads would probably run out out towards the top of the hole.
And yes, straight threads seal with a crush washer. A lot like the stock coolant sensor. Looking for an adapter with as large a face as possible would also be a good idea.
Also looks like there's some taper seat M10 adapters mixed up in those links, the auzzie one. Those won't have a spot face, and so won't seal on the combo pressure/temp sensors very well. I think those are predominately direct injection pressure sensors, 1KPSI+
There is a diagonal edge on the end of the combined sensor, but the temp sensor protrudes from the tip. I am wondering if that is intended as a sealing taper? You would also be relying on the sensor screwing all the way in to get a washer under the flange. I need to get one ordered and have a look at it - based on watching their videos, I think haltech buys a lot of stuff from EFI Hardware, so if I were a betting man I'd throw a fiver on the haltech one being the same as the one supplied by EFI Hardware.
They are the same as any other 4.2/4.9/4.9ADV sensor. They usually just have proprietary plugs on end and are a real ************ to adapt. The 2013 volvo C70 has a bosch 4.2. Pretty sure it would be cheaper to try and fit an aftermarket 4.2 sensor to it than buying the volvo branded part. A 4.9 does not have a calibration resistor and would be a million times easier to adapt, you cannot cut the plug end off a 4.2 sensor...
And as I said earlier a NPT port is tapered. The major diameter at what would be the spot face is too large of a diameter. To make it work with full thread engagement you would have to sink the M10 and spot face past the original. If there is enough vertical room, it could work.
On my FPR going any deeper is a no go, plus the damn thing is round at the spot face so it would never seal. An adapter would be the only way.
PST 1 (0.1 to 1.15 bar) - Bosch P/N 0261230333 - Used by several Ford products, including certain F150s. Available right now on RockAuto for $25. PST 3 (0.2 to 3 bar) - Bosch P/N 0261230280 - Used by some Fords. Out of stock on RockAuto, available at NAPA for $30. Ford PN EL8A-9F479-CA PST 4 (0.4 to 4 bar) - Bosch P/N 0261230423 - Used by Volvo. Available on eBay starting at $16 ($35 from more reputable sources). Volvo PN 31405341
I'm thinking of using the 1 bar sensor in my K24 swap. Seems like killing two birds with one sensor. Any reason these wouldn't be better than individual sensors?

Awesome thread! I have been scouring the web for some details about implementation of these sensors, and a random hit landed me in here. I have 2 of the Bosch PST-F1 sensors on order, and am going to need to machine some adapters. The big thing I am concerned about is the sealing method. Per the datasheet, these things have a flared end which is supposed to bottom-out in the taper at the bottom of the hole (shown in the official data sheet, in a lousy drawing which is missing proper detail lol).
Anyway, my thought was also to just get a copper crush washer in there and seal this thing the same way that the oil pressure switch in my engine is sealed. However, silicon pressure sensor elements are super sensitive to stresses in the surrounding structure, and I am not sure if putting all of that loading on the bottom boss face is going to mess up the calibration and/or lead to premature sensor failure. Has anyone here installed one of these with a crush washer and had positive results? I've reached out to Ballenger Motorsports and EFI Solutions (resellers of the sensor) with the same question, but I expect to get a CYA response saying that they can't guarantee anything. I bought mine from EFI Solutions, which sells them for AU$99, beating any price anywhere in the US. Even after the $30 shipping they are a solid deal, especially if you are buying a number of sensors & parts.
If it comes down to it, I can machine a flared-bottom adapter per the "official" documentation, but that is going to be a much bigger pain than just drilling the existing M12 hole out to M14 and stuffing in an M10 thread insert. As for implementing the sensor in the fuel system, that is all custom machining anyway, so anything goes there.
