I am installing an Old Britts gauge kit. Either I am goofy, or there is a design issue. I cannot seem to stop the banjo connection at the bottom of the standpipe from serious leaking. The directions specify not getting the nut at the bottom of the standpipe very tight as it will damage the gauge. But, the bajo bolt needs to be tighter than is possible without cranking down the standpipe enough to destroy the gauge or the seal. I tried new copper washers with annealing and without. The OB paper says he prefers aluminum washers, but I'm not seeing those anywhere. And, the fearless leader of the loval group swears by annealed copper. What say you guys who are likely smarter than I?
 
Whenever I’ve had oil leaks, aluminum crush washers have worked when copper hasn’t.

I'm confused about where you are leaking. If at the gauge - I have no clue. If at the head, then the nut has very little to do with it. Look at the inside of the rocker spindle cover. The threaded part must not go past the inner edge, or you'll never get the plate sealed. Also, ensure that the rckeet spindle is turned so the raised placed on the cover go into its slot with the screws installed.
 
I have had to reuse odd size copper washers before. A little sandpaper to make them flat again. Then anneal it. This has bailed me out many times.

Put a PRECISION square on the end of the tube. Seems I remember it was saw cut, and not exactly square, and threaded O.D. & I.D. but the end needed filing smooth and square.

Also, I coat the crush washers with Loctite 518

Leaking at the banjo at the bottom of the frame neck. That's where the tube from the gauge meets the line coming from the cylinder head.
