Fuel line replacement, What to look out for Options

[DavidSweden]

I am currently repairing the rust / replacing metal on the driver side longs and floor pan. While I have the car up in the air and the engine out I would like to replace the plastic fuel lines that go thru the tunnel, the car smells of gas and i dont want to risk a fire

Questions;
I was thinking about using 6mm stainless tubing. Is the choice of tubing good?
It seems a pretty straightforward jobb, is there anything I need to consider/watch out for before pulling out the existing plastic tubes.

Thanks

I used,truck metal brake line tube through the front bulkhead grommet,good quality hose and the correct fuel line clamps.
Pressure side was redone in rated (blue) plastic line from a VW Golf,correct inner ferrules fitted @ all the flexible hose joints.
This was easy to run and I now it is going to last,however my original plastic lines were in good shape,the rubber jointing hoses less so.
As I'am running carbs I ran the pump power supply down the old return to the engine space.
