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 just measured Chris' lines today the supply was around 9.5mm OD and return a bit under 8mm. Both the short lines are the 8mm.
Likely they are standard size tube that is close to metric.

Are the plastic (nylon) lines shot? They are pretty tough and I doubt they would ever be an issue if they are run at low pressure, stock pump location. Most fires are more bad clamps, connectors and old hose issues. You could just replace the high pressure short runs in the engine bay.
If you did do the front FI pump then yes, replace them.
