Thank you for your interest.

But but I need to know threads and diameters of the unions which are welded on the separator to fit adaptors for goodridge hose fittings : BSP to JIC or metric to JIC? And which size they are ( 3/8? 1/2?)



And on this image:



It seems that hoses are:
-AN10 x2 , one from exhaust side of the block and one for breather to atmosphere (or catch tank) ;
-AN8 x1 for return to sump and
-AN12 x1 from admission side of the block.

I don't understand ...
