I don't get it why put it on if it had shit welds and didn't fit how you asked it to do why not send it straight back, inspect all welds before it goes on but at the same time it's just fell apart, the heat has just pulled it apart, he should make you another or at least refund you for your troubles to get another manifold, hope you's settle for a happy agreement Zisco can be great they have done great work but this needs attention definately :-/
