Just wanted to no what the thread size was,

M10x1
M12x1
M14X1.5
M16x1.5

Maybe smaller?

 

Whatever is closest to 1/8 NPT, I think. My SPA pressure sensor threads right into the stock brass spacer thingy quite well. They are probably not precisely the same thread, but you wouldn't know it by putting them together. And I think the SPA pressure sensor is 1/8 NPT.

EDIT: I used the stock brass spacer thing. I am not sure if the threads are the same in the engine housing itself.

Thanks for the input, anyone eles have a comment

 

after i have finished my gauge install i can close this thread by saying that the thread size is 1/8 on that extender that the oil pressurer sensor is on. No need to buy an adapter.

Thanks All
