Things You'll Need

  • 13 mm socket

  • Needle nose pliers

  • Large bucket

The gas tank on a LX255 is located under the operator's seat. The tank hold three gallons of fuel. The fuel system is run by a mechanical fuel pump that bolts to the side of the engine block, it draws the fuel from the gas tank, and delivers it to the carburetor. If water or debris gets into the gas tank it must be removed to keep the engine running a peak performance. Removing the gas tank is the best way to drain the tank. This procedure will take 15 minutes to complete.


Step 1

Park the LX255 on a level surface and set the parking brake. Remove the key from the ignition.

Step 2

Lift the operator seat; disconnect the wire on the seat switch from the wiring harness. Remove the two 13 mm nuts just behind the seat that hold the fender deck to the frame with the socket wrench. Pull out the mower adjustment knob in the middle of the fender deck just below the operator seat. Remove the two 13 mm bolts under each foot pad on the fender deck.

Step 3

Pulls up on the back of the fender deck, and then pull the fender deck off; this will expose the gas tank. Disconnect the fuel line from the top of the fuel tank with the needle nose pliers and wipe up any fuel spilled.

Step 4

Pull the transaxle reservoir up and out from the right side of the gas tank. Lift the fuel tank off the machine and twist the fuel cap off. Tip the fuel tank over the bucket and gently shake it until all the gas is drained out. Installation is the reverse of removal.
