Replacement of gas tank on a Sears GT3000 riding mower

I ordered a new gas tank for the mower, because there is a crack in the tank now, no leak yet. I haven't been able to work on it due to knee surgery. Would like to find out the easy and fastest way to replace the tank.

If theres no leak yet you can easily patch it with an epoxy puddy, available at your local auto parts store. i've used it myself on gas tanks, radiators, boats and its never failed me yet

Why is gas leaking out at bottom of the tank where tube connects to gas tank?

If you have already replaced the clamp and tightened. The tube itself could be cracked. Loosen and bend the tube and inspect closely to see if cracking or split opens up. If it does then replace the tube.
There could also be a crack/hole on or near the bottom tank connection. This can be difficult to locate but holding the hose barb on the bottom with a finger and pouring a little gas into the tank.
The hole/Crack should be easy to find. Vibration will sometimes cause a crack in this location. Typically I suspect the hose.
Today's gasoline is notorious for degrading gas lines due to the additives and ethanol from corn.
Good luck hope this helps

Gas tank leak

The gas tank would go with the engine. Find the engine number (Briggs & Stratton?, Kohler? ) You can order it online from Briggs & Stratton parts, or like Jack's small engine, or your local mower parts supply. Common poblem with these plastic tanks.

Gas leak in sears lawn tarctor model

You will have to remove the seat and then the platform where the seat mounts, this will give you good access to the fuel tank. I know it looks like a daunting job but there are only about 8 or 10 bolts that hold the entire thing on and if you look it over before you start to find all the bolts, you can have it off it 10 or 15 minutes.
You can go here if the link works and see an exploded view of it:
Type in your model number then select Chassis and Enclosures
