Diameter of front to rear brake line?

[andyfanshawe]

Does anyone know the outside diameter of the front to rear brake line please? Van is a 1992 4 wheel ABS.

Reason? Rotting out and need to replace.

Thanks.
Andy.

if you still have the old brake line throw a wrench on the line to see the outside dia, not sure if its 3/8 or 5/16"

my 98 is 1/4" if that helps at all.
