wastegate vaccum thickness??

[bvtec]

what thickness should the wastegate vaccum line going from the wastegate to the intake manifold be( 3.5mm,4mm,6mm etc),
if it is a certain size should the other vaccum leads eg. boost gauge/bov etc leads be the same size.

All my vacuum lines are the same as the one that came with the greddy boost controller. That doesn't really help all that much but whatever.

1/4" and 1/8" is 98% of my vac system.
