I plan on sending you one of my 1100 sacs that had this done at the dealer. Now why in the hell would my dealer cement one sac's fittings and not the other is beyond me. Also, I'll request a second fitting be added to the top of the sac. As it is, my 1100's have a fill and vent on top. However, I want to add the 3rd top fitting so when switching surf ballast from side to side I can assist my stock pump by using the Tsunami 1200 draining one sac and connecting the hose to the sac I'm filling...thus killing two birds with one stone and fill/drain times cut more than in half.
