Whoa, it would scare me too. The recommended higher strength flushing acid around here is diluted muriatic acid, not sulfuric acid. Store bought muriatic acid runs between 10-30% concentration and after diluting it another 1:15 per the Moyer instructions you're close to 2% before drawing it into the engine.
