Does anyone know what material the manifold is made from? I like to try/learn things myself before sending it to the shops, I have a decent inverter arc welder but isn’t sure what material the manifold is made from, seeing that the brazing was a flop I just need to confirm the material then I can get the right rod for the job, if I don’t come right then it will be off to the shopsI don't think you can braze that!
That part gets super hot and could crack again if you just braze it.
What Phillip said; take it to a welder and get him to tig or ark weld it.
Man, that's a lot of water!
