x2.... has he used the bow ballast successfully yet? From the factory the bow ballast is just a fill pump, drain pump, and all the lines (fill, drain, and vent) and they fill and vent lines are looped together until you install the front sack.
If you have the sack installed, then pull the bow seat cushions out and watch to see if it is filling at all, check the hoses and make sure it is all routed correctly.
