oil pressure gauge and line

I can't figure out how install my oil pressure gauge and line on my TR3A. Not the dashboard end, the business end. When I took the car apart 7 years ago, I took a bunch of pix, but can't see the area around the oil filter. Moss supplied me with a solid stud that the engine end of the oil pressure gauge line apparently attaches to, but I don't see how that would allow oil pressure to register up the line. I know I'm missing something, but my old brain is failing me. There's not a TR3 nearby to go look at. Help!
 
The aluminum filter head has a groove in it, that allows oil to flow into the cavity where the stud goes through the filter head. Oil flows through the hole around the stud and into the banjo. If memory serves, it's the short stud nearer the front of the engine.

Should be two different sizes of copper washer, the larger one goes between the banjo & filter head. Also a special "capped" nut, so that oil doesn't leak out through the threads.

Sorry I don't have a photo handy, but maybe someone else will.
 
The line goes around the stud with a banjo bolt, two fiber washers, and a special cap nut and picks up the oil pressure there. It can be confusing until you see the whole set up because the stud is solid. The oil comes out of the pressure regulator hole right at the stud and the cap nut and washers seal the system at the regulator. Sorry no pictures, but be patient someone will have one.

Sorry, I posted my inquiry twice. Couldn't find the first one, so I asked the question again. The groove in the oil filter housing is what I couldn't see now that the engine, etc. is installed. The groove allows oil to run up the pipe and register on the gauge. That makes sense, although it seems to me to be an odd way of doing it. But, it's a 50+ year old Brit car.....why would it make sense to an American boy.
