Does anyone know if aluminum fuel lines are permitted for IVA?

im sure they are used on some production cars so would have thought so, good luck bending it perfectly though, imo i would stick to tried and tested path.

With the increase of the Ethanol content of Petrol to up to 10% then corrosion of Aluminium fuel pipes could become a problem.

In the past I have used Aluminium hard wall tube which had a plastic outer coating.
