Make sure the vents are clear, at a certain point it will vent out excess fuel.
It's not unusual for a little bit of fuel to burble out of the jets after shutdown but dumping fuel on the chassis suggests somethings wrong.
Even when I alter from stock, I still route the fuel lines in the same location, if for no other reason than that it's simple to service and nothing in the way.
Just a few thoughts, doesn't answer your direct question though...

I think that every Triumph I have seen runs a fuel line around the front of the engine up at the level of the T-stat housing then drops down to the carbs. Why not run the line lower where it wraps around the front of the block? I am assuming that with the old TRs having the big belts there is the possibility of the belt or a pulley hitting the fuel line but with the 1/2" belts there should be plenty of room shouldn't there?
Why is this of concern to me? The fuel line is obviously full when the engine is running. When the engine stops the fuel in the line isn't going to stay there, it's going to drip down into the float bowls. In the case of the GT6, I have an inline filter just before the carbs. The fuel from the line and the filter is draining down and overfilling the float bowls when the engine stops. That fuel is dripping onto the frame. It's also likely to be the reason I found fuel pooled in the intake manifold when I removed the carbs this past weekend.
Have you or anyone you know modified the fuel line routing so it is always going "up" instead of down? Inquiring minds want to know!
