fuel cell to motor fuel lines advice please

[82Cecil]

82 C 10 short bed

Planing to locate the fuel cell under the bed behind the rear end and locate the bypass regulator and areomotive A1000 pump close to the fuel cell.

This is a carb set up.

I would like to run an 8an or something close to it, from the regulator to the motor in a steel line. maybe 12 or 13 feet. ( bypass close to tank )

What is the best way to do the fuel line(s).

Thanks for your help.
