    Hmmm...….Not sure how to measure how much fuel gets shot out.
    It's a decent stream.

    Not entirely sure about the bubbles in the hose- the carbs are "fuel on demand", pretty sure the pump draws fuel from the bottom of the jet block- my first impression would be there should not be air bubbles.
    Air is compressable, where liquids are not. I'm guessing Air bubbles would reduce fuel spray.
