Thread sizes anyone?

[GAF2]

Orite guys need some info on a couple of thread sizes, firstly the oil filter thread size is it M18 or 3/4 UNF and also the oil pressure switch thread size.  Looked through my haynes and it doesnt tell me anything.  Any help much appreciated.

cheers Grant

i THINK the oil pressure sensor is an m10x1 - same size as a brake unions as far as i know!

cheers bud, any thoughts on the oil filter?

[hayesey]

yes the pressure switch is 10x1mm thread, same as standard metric brake pipe fittings.

Not sure on oil filter but I think it's 3/4 -16 UNF.
