I don't understand why instead of doing the T mod you wouldn't just route the hoses under the seat with nothing point down?
(I know there is a reason - I just don't know what it is...) Does it blow/push and then get backed up under water and for that reason having an alternate route under the seat allow it to work when water is up to the bottom of the hose?
