Vacuum hose sizing

[Grant]

So both pairs of digital calipers have dead batteries and I haven't been able to find this info out there.
Anyone know what size of vacuum lines are used on the EJ22t for connection to the stock fuel pressure regulator. It's tiny and way smaller than usual vacuum lines like the one to the wastegate.
Thanks in advance.

I do not know the size off the top of my head, but here's a bump to the top.
