As Steve said, nothing stops water running down the tube as I found out when I had the seat up to fit a new in tank pump. The pipe had gone rotten,and crumbled in my hand. Luckily no damage had be done other than the tube.I bought some expanding foam in a can, and sprayed it from the inside of the tube until it came out in the wheel arch. I then levelled it off and sealed it with under seal.I think everyone should check this spot for damage.
