Im replacing both tanks on my 25 Sailfish and the (very reputable) mfr. suggested redirecting the hose barbs aft so the line doesn't sit on top of the tank as much as the original connfiguration. I said go for it, can anybody think of a reason not to? The reason I'm replacing is that the main tank corroded a quarter-sized hole on the topside. E-10 + H20 + VST = no boating this summer.
