I am in a progress of making my own oil temp gauge, what's the size of the sending unit thread pitch? TC96 motor Thanks!

 

Check out this Dakota Digital link - 1/8" NPT should confirm your answer http://www.dakotadigital.com/index.c...rod/prd329.htm

 

Should be 1/8" pipe thread .

 

Thanks!

 

Pretty sure it is 1/4 npt, that dakota link even says it come with a 1/8 to 1/4 npt bushing.

 

The " bushing " is used to adapt the smaller 1/8" male thread to a larger 1/4" port , the gauges themselves are almost always 1/8" male thread .

 

The OP was asking about the thread on the sending unit.

 

The sending unit is 1/8 npt, found it! http://www.ebay.com/itm/Dakota-Digit...383278&vxp=mtr
I think they include a 1/4 npt adapter for different application.

 

Ok, quess I am confused. I thought you were talking about a stock sending unit.

 

Yep, just pulled mine on '04 Dyna to install a press gauge. 1/4 NPT (18 TPI, -4AN). Only know cause I had to go to Lowe's to get a brass pipe plug to eliminate the OEM sender on the adapter block.
