Wouldn't a Fass 165GPH be too big for something that isnt going to be pushing ALOT OF HP? Also, other than noise, why a sump? That's taking even more money out the better mods rainy day funds
that flow is several times more than you need, however it also wont hurt anything. You could drop it down to the 95, and you would see no changes in performance, however if you already have the 165, run it.
