Check out this high-pressure injection bar! It’s a unique design that uses c-clamps and jacking studs to position and compress packing on a steel bar in a tight space. An ideal design to seal an inaccessible leak to a peening chisel. Essentially, they were peening the flange and injecting, but the leak chased behind the alignment bar on the top flange. This design bridged that gap and ultimately stopped the leak.
