I agree with the bulk of that except for two points: > At no time, with the exception of a situation such as that involving the FCR choke circuit, should there be a really significant volume of air moving through these lines. There is a big difference between upsetting the atmospheric pressure balance within the float bowl enough to make the engine falter and moving a mass volume of air. > The unit is, IMO, shall we say, just a bit overpriced at $40. Pretty colors though. OTOH: > Over time, enough very fine dust could find its way in by this route to be noticable. > Running two of the upper vents to the air box absolutely will stop water from being pulled up. Be sure to filter these hoses. Air boxes are pretty funky.
