I am pretty sure that the outlet is not 1/2 unf 20. I bought a hose tail that was 1/2 unf 20 and it doesn't fit, it goes about a thread and a bit before it gets tight. Looking and thinking and measuring multiple times, I am starting to think that they outlet may M12. The Thread pitch matches 1.25mm, which is right for an M12 Bolt/Tube Nut. Also, the MK2's were assembled in Germany, they have been metric since before the War, so suspect that they connectors are more likely to be metric. Of course, there is always the chance that a few old tanks were put together with imperial parts in the UK and then shipped out to Germany, so there is always a chance that some of them may be imperial. This at the moment is the straw that is breaking the camels back, I can't reassemble my tank without a decent tank outlet connector, so if anyone has any ideas they would be gratefully received. I really don't want to start with the welder as the chances of totally fluid proof welds are slim.
TIA
