Is it 3/8" or 5/16"

I cant remember the size of fuel line for Yam type connectors is it 3/8" or 5/16" got to get some to pipe in the fuel flow transducer recently fitted.

I think it has to do with who rigged it and how it's rigged, but my 115 used 5/16 (had to modify the way my Racor was plumbed in when I changed the mounting base from Aluminum to SS.)
