    fuel lines for twin side draught weber 45's

    Can anyone tell me the correct inner diameter for fuel lines for twin side draught weber 45's ? I need to run all new lines from the tank to the carbs.
    Also is the stock fuel pump adequate for this setup?

    Stock 8x13mm (5/16) fuel line.

    In theory stock mechanical pump should work, but better is low pressure electric pump and fuel pressure regulator set at 2.5psi.
