Hello!
Do you know if graham goode racing oil separator adaptors 3 ports are BSP or metric? and which size ( 3/8? 1/2?)

I think that hoses are -AN10 from exhaust side of the block and breather to atomosphere ; -AN8 for return to sump and -AN12 from admission side of the block.

But I don't know the thread and diameter on the separator to fit adaptors for goodridge hose fittings

Thanks !
