I use a similar brazing rod from Lincoln you can get at Home Cheapot for about $4 plus some dip-flux. I prefer to add the dip-flux for better coverage. Mine are usually steel-steel.

Is there some advantage to brazing rather than welding? I've made many a fuel rail and I've always welded it.... had never even thought to braze.
Am I missing something or is brazing just a cheaper method (don't need a TIG machine)?

Brazing has the advantage that the solder or what's it called flows .
And it can be applied with little heat compared to welding , wich reduces
warpage . Also , it doesn't take to much skill to braze or solder .
Mag welding does takes some skill to get it all leak free .
An acetylene/oxygene welding torch offers the advantage
of the metal flowing continuusly , like a bazing process , but
introduces to much heat to the rail .
A tig is kinda best of both worlds . Nicely controlled melt , not to much heat , argon protection . Now that I own a tig , I wouldn't even consider brazing or acetylene welding anymore .

A big plus for low-budget DIY MSers is that brazed factory-style rails can be made with just a $30 MAPP torch kit, rods and simple tools. A whole fuel rail could be made for under $50 including the equipment!
