Hi, me and my son are putting a 22re in his 74 pickup, the engine is out of a 90 pickup, what adapter will I need to install the sending unit in the same place I'm removing the original sending unit? I haven't bought the temp gauge yet, just want to have everything I need before I try and install it ....any help is appreciated
Anything that is 3/8" will be Japanese spec but anything 1/2" will be npt. You might have a port you can use.
I'm not using the original sender that was electronic , should be able to adapt to that outlet, just not sure what thread it is,
Depends on the size of the probe. With an adapter you step it down some. So if it's only a little smaller then the threads it will not fit. The British standard will work thought and easy to find.
Most early Toyota thread has a 1.25 pitch. So either M8x1.25 or M10x1.25. Depending if it’s a nominal 5/16 or 3/8.
