This bit proved quite a challenge.
There are two take off points on the Chevy SBC, one is a 1/4 NPT just above the oil filter and the other a 1/8 NPT on the top face at the rear of the block.
neither are particularly accessible but I decided that the top one was the best prospect.
As I have two senders to accommodate I needed a T-Piece to attach them. This took a load of research to find an adapter that was narrow enough to clear the inlet manifold. I eventually found one from CBS. This one is 18mm across flats and I thought would fit. In the event it turned out that I had to file the bit nearest the screw in end as it was catching against the
manifold.

Next problem was that with the sender fitted in the top. the assembly was too long to fit underneath the distributor.....
So - plan B - I purchased a 1/8 NPT tap from Amazon and drilled and tapped another outlet on the shank.
As I'd filed the sides down a little, it started to rust in no time so a quick coat of Hammerite was needed.
