Stock fuel feed line as return?

[3.8vsix]

I am planning on upgrading my fuel lines and was wandering what I can use to attach the 3/8'' feed line (using as return) to the 5/16" hose at the tank? Does any one make a barbed reducer for gasoline? BTW I tried the search and did not find a clear answer for this. Thanks for any help!!!

Check nearest parts store for that fitting. Brass fitting section will have it

Just wandering if there would be another way to run the the line in the tank without going from the 3/8'' hose down to the 5/16'' hose. Seems this defeats the purpose of using the feed line as a return if you have to neck it down. Any thoughts?
