Interestingly, I found a label on an AEM water/methanol injection tank that says, "Do not pump flammable liquids", yet they say, "Do not use mixtures containing more than 50% methanol". So, I wonder if all pump manufacturers place this label for liability reasons. I also understood that a 50/50 mix of water/methanol was flammable. For fun, I watched a few youtube videos of folks trying to ignite windshield washer fluid. None seemed to be successful. That said, I had one leaking connection on a fitting mounted on the upper support. It was a minor, almost undetectable drip, but the airflow into the engine bay left scattered droplets on the intake manifold. It speaks to the importance of a) making sure the system is tightly sealed and b) that a nonflammable concentration is used.
