How big of a job is that to replace?[/QUOTE
fuel pickup and fuel return hoses go into top of the tank somewhere between the engine and hydrostatic pump (actual location was moved a couple times throughout production of this model due to design changes). Usually it is tuck up close to pump. The barbed fitting going into the tank passes through an expandable rubber bushing. To Remove; pull up and twist the bushing. It will pull out. Use a new bushing when you reinstall. If the pickup tube is hard straight plastic type most dealers replace it with hose about 1.5 - 2 times longer than original tube and install p/n 6650239 brass fuel screen on end of hose.
