If you follow the hose from your impellar (water pump), you should find it. On a Malibu it is not far from the pump, not sure if it is similar on the Mobius. You are looking for a metal cylinder that is slightly larger on one side than the other, should be a hose going in and coming out. I take mine off and clean it every couple of weeks to remove weeds, takes 30 seconds.
