I need to know the thread size in the crankcase of a 3TJ for the oil pressure sender as I'm fitting a gauge to my bike.
It looks like a 10mm x 0.9 pitch with a taper on it, does anyone know for sure so I can order the correct adapter? 1/8 5/8 BSP????
Thanks chaps

take the original send unit to a hydraulic hose company and they will match it for you, loads about.
