Front union to flexi hose brake pipes

How were the front union to flexi hose brake pipes originally routed?

I have a pre-assembled copper brake pipe kit. The pipes in the kit are much longer than the ones I removed, which are obviously not original.

The green book has a diagram of the brake system, but where the pipes should go is not very clear.

Thanks for any info.

my series 3 ones ran drivers side on top of chassis to hose , passenger side to front then across chassis and back to hose can be seen in this pic.

Thanks for that. So the pipe to the passenger side should run along the back of the front cross member?

yes

I did a bit more on these today. This was a ready made kit of pipes which were supposedly the right length.

Now I need to get a tube cutter and flaring tool.

Is it preferable to route these undeneath the main chassis rails? This is so that the bottom edges of the wings don't rub on them.
