I'd call Mr. Morad and get a rail or braze your current one like stated by others. Curt mentioned 50% silver solder, we use 100% silver solder in my shop with the torches we build and it'* really strong stuff.
I went out and bought some MAPP gas and brazed them today. Turned out pretty good I think. Don't see any holes, but after they are cooled down a bit I will pressure test them. I ordered my AN fuel lines today from Jegs so hopefully I can get this project going next week.
Here is a pic of the progress:
