MitsuStyle - View Single Post - Need help fast! Oil pressure gauge install trouble

**asshanson** · 05-29-2008

Well you said yourself that the stock and aftermarket gauges both screwed into the NPT adapter the same. Anyway, I have a different oil filter housing, so the threads could be different.

I just did some reading on British pipe thread, seems it's very close to NPT, one thread per inch less for 1/8" size. Retapping sounds pretty safe.
