I know the lines mustnt be run together in the transmission tunnel. But is there any problem with them crossing over at the back of it? I dont think I can avoid it at the moment. I cant find anything in the manual...

Cheers,

I hope not!
I can't avoid it at the front so I'm hoping it's ok!

It is often unavoidable to cross over and as long as you show common sense I don't see a problem.

My fuel pipes (8mm steel) run along the top of the transmission tunnel with the electrical loom and brake pipes running alongside.

There's a gap of about 80-100mm but it wasn't a problem at SVA and will probably never be a problem in real life either.
