Mep-806A coolant temperature sender source needed

[Ray70]

Hello,
I'm working on an 806A for someone and the coolant temp sender in the corner of the head is broken. ( somehow the wire and center pin have come out of the casing and were dangling behind the head )
Looked in the TM and it gives a PN of:
Beede 127341 , 5905-01-376-0985 , 88-21742
Unfortunately a google search of these 3 numbers really didn't find me anything that is correct and available.
I was curious if anyone knows of a source for one, or if there is a known replacement that works?
I was also thinking that since the gage in the 806 is the same as the 802/803 etc. I wonder if the sender from an 802/803 would work if I find a brass bushing to step up the thread size to the 1/2" NPT needed for the 806?? Should use the same resistance range I would assume.
FYI, the TM says the sender should be >300 ohms at ambient and drop as engine temp increases, that's all I found for specs on the sender.

How about something like this? https://www.amazon.com/Sierra-18-58...ocphy=9001652&hvtargid=pla-492542038931&psc=1

Edit: No, it wont work due to the right design. Correct temp and mounting threads I think though. Id look further into what Sierra offers... I have used their oil pressure senders before, seem to be as good or better than OEM.

This appears to be a single station install:

Sierra Marine TS26631 Temperature Sender 1/2" NPT

Sierra Marine TS26631 Temperature Sender 1/2" NPT

Go to the Faria web page and see if they still have a NSN cross ref listing, with that NSN or part numbers on it. I will see if I can dig deeper after launch.

I found the old NSN cross list for gauges, but I didn't see one for senders. If you look at one of Farias later catalog releases: https://fariabeede.com/site_manuals/Faria_Beede-fm-002-0001-2019-Aftermarket_catalog.pdf

They do have different temp senders listed... one of which appears to be workable? https://recreation-outfitters.com/p...nder-1-2-nptf-american-single-standard-ts4042

Great info guys. LITD, It's funny you mention Sierra, when I was searching by PN several listings for the Sierra Marine senders came up and I wondered if it might work. For $18 I might as well give it a shot, I also have a 240V temp gage on the shelf that was in an 803 I bought years ago. It was not the right one for the 803 ( apparently a different operating resistance ) maybe that would even work with the Sierra sender, if it doesn't work with the Beede gage.

Here are a couple more data sheets from Faria Beede.....resistance values and American vs Euro values.

Excellent documents right there

I know right! That's exactly what I needed Zed.

So I went to purchase the Sierra TS26631 and the particular ad I was looking at said it is comparable to the Beede F90404 from LITD's attachment above.
For the sake of an extra $4 I went with the Beede, seeing that the gage is from Beede, why not keep it all in the family!
I will let you know once its installed, but I'm thinking this will work.
