fuel line: over or under?

Spridgeteers,

With the engine out, I'm pondering a few things. My fuel line runs 
below the transmission tunnel. It's clearly snagged various and 
sundry items over the years. Is there a reason why the line should 
not be run on top of the floor of the transmission tunnel, where it 
would be protected?

TIA,

Jeff
