TR2/3/3A TR3 Oil filter head, long stud?

Among other little assemblies that I have been working on is the oil filter. Fairly straight forward. Couple of NLA copper seals were a bit of a problem but finally got that solved and was installing the filter head. I saw a stud in position (see Attachment) but the book shows four cap screws and what I have is three cap screws and one stud.

Anyone have any idea what gets attached at that point?

Your thoughts deeply appreciated as always!

Thanks, Tinkerman

Your banjo fitting end of the oil press line goes there with crush washer on each side and cap nut.

There are two copper washers. The inside washer has a larger center hole to let oil that passes from the engine, around the stud, through the banjo, and on to the oil pressure gauge. The second washer is fit to the outside of the banjo and an acorn nut usually secures the banjo to the stud.
