My sending unit has died. has anyone determined which one will work like from Napa?
If not does anyone have a military one for an AO with a 3116?
I would prefer new.

Do you have the part TM? The part number called out is 506AZ and a quick interwebs search comes up with this here https://www.finditparts.com/products/11748022/stewart-warner-506az Don't know if that is the correct one but the number matches. Take the number to NAPA and see if they can cross.

97' 3116 oil pressure sender

I have a 97 LMTV with the 3116. I have crappy readings for oil pressure. I checked with my mechanical tester to verify. I am looking to replace the sender, after checking wiring and cleaning up the connections. The part # on the current sender is 12420859 with another mfg # of 7z634. TM-P #...

Thanks I will call them in the morning.
I think this is exactly the information I was looking for.

That part number is the U S Army Tank Automotive Command and the number that Stewart and Steveson/BAE uses. That number can be hard to cross. The TM gave the Stewart Warner part number. Some times the TM only gives the U S Army Tank Automotive Command number. The best way I found to get a number that you can use at like NAPA is get the NSN from the TM, Use the NSN on a website like this here https://www.parttarget.com/6620-01-...6az&searchoption=sku&originalsearchtext=506az and you may see a number you can use. There is a lot of info on that website and I find it invaluable for researching parts.

does anyone know how to tell if it is the sender or the gauge? should the gauge be full scale when the sensor lead is shorted and 0 when connected to 24 volts?

Yes. The gauge, when powered, sends current from the sense lead, thru the sender resistance to ground. With nothing connected to the sensor lead the gauge should read zero, if you ground the sense lead it should go to full scale…
