In industry I used nylon and polyethylene tubing for (150 PSI) air supply lines routinely.  The plastic tubing is certainly up to the task and compatible with fuel.  However, as Jedduh01 said, cunifer is a good choice which will be less prone to under-car punctures and it will have enough stiffness not to sag.  That is the route I would go.  

You should be able to jack up the left side of the Mini and put it on stands to access the under-car tabs for the metal line.

I would see it as a fine solution if done Correctly.  
  Metal line sort of holds its self up in place against the bottom of the car and the floor pan.  A nylon plastic line will sag much more, youll need to affix it better to the floor of the car with hardware or tabs in more places.
  Modern cars also usually have a tray/shield that hold and also protect the lines together.

There arent many tight bends in a normal Mini fuel  line run but if you go up and over the rear subframe like stock  those tight bends Could cause an issue if not planned or perhaps help the nylon bend around.
  
Cunfer Metal lines are also a great alternative to steel.  Available online in a 20-30 foot coil... bend easily and are still Metal like a steel line would handle.

Has anybody tried to use a modern nylon fuel line in a Mini, rather than the metal stuff?  Most modern cars are using this now but I don't know if it is a good idea due to the way the Mini has the fuel line routed under the car.  I need to replace my fuel line and do not have a lift.  Due to the flexible nature of the nylon line, I thought this would be a good alternative.
