The "T" will allow the carbs to breath when lower is under water, (so the tee'd off bit will be under the tank & dry) and also let it drain any excess fuel off.
As for that plastic bit - its called a "carburettor suction pipe" !!!!! No extra bits come off it. So may well be worth adding a pipe to it & routing it up higher & see if that helps??? I was wondering if its some sort of valve thing thatb shuts off - like a ball in it or something?
Let us know.
