I just joined this forum and I don't have a whole lot of machining experience so I'm looking for some good'ol practical advice.

I am modifying the fuel cross-over line from my VW van because the nylon fittings are breaking every few years. These little pieces of plastic end up costing $64+ for a replacement and I'm done shelling out that kind of cash for plastic that doesn't last. So I am going to a brass fitting but I need to modify it slightly.

The plastic fitting has a 0.4" long shoulder which is 0.5" in diameter and I need to recreate that on the barbed brass fitting. See pic.

What would be the easiest and most cost effective way to achieve this? Would I use a lathe or a mill?

My concern if I use a lathe is how to fixture the part because it wouldn't be balanced.

Thanks for your help.
