Yeeeeeeeeeah ok.

Back to the subject.......did you hook your blowdown tube up the the purge solenoid? Please say no..........the blowdown tube mounts to the valve on your bottle......when the pressure exceededs the valve, the blowdown tube lets the gas escape.....and carries it out of the car. Your "kit" should have come with a thin brass tube that you could bend to accomodate your purge line. For the amount of line you have, nothing sounds out of the ordinary as to it taking 3 or 4 seconds to exit the tube.

As for wasting nitrous..........would you rather make sure the condensation is out of your lines or take the risk? Thats what it is there for........what you hear but cant see coming out of the purge is air.
