fuel line sizes

Howdy, I'm trying to find out the inside diameter of the fuel lines for the inlet and outlet of the external fuel pump on an early model 325e.

I'm pretty sure the inlet is 12mm, what about the outlet though?

if you look up part #s for the hoses on realoem.com it usually says the size of the hose.

good call, had to try a few different build dates to find one with the same fuel pump part number and both hoses labeled with a size. 12mm in, 8mm out. someone correct me if i'm wrong though.
