To replace the fuel tank, the mudguard must be removed from the frame. Remove the screws that secure the screen to the frame or mower frame. Remove the saddle and loosen the shift knob. Lift off the screen part of the frame and you can replace the fuel tank.
Find the fuel line connections on the lawn mower. One connector is on the bottom of the fuel tank and another on the engine. Remove the fuel line ■■■■■■■ at the bottom of the tank. To do this, the clamp is tightened on the fuel line and moved away from the fuel tank.
The E10 can be used in all current Husqvarna devices, but we recommend using E10 gasoline with at least 89 octane, which is halfway between regular gasoline and gasoline.
Empty the fuel tank. Unused gasoline left in a lawn mower over the winter can age, corrode the rubber in the carburetor, and cause rust. First add the fuel stabilizer to the tank, then operate the mower to distribute it throughout the system. Turn off the lawn mower and allow the engine to cool, then sip the excess gasoline from a clean can.
Let the mower run out of fuel. Remove the fuel line from the bottom of the fuel tank the same way you made the carburetor in step 5. Place the old fuel line next to the replacement line. Cut the new fuel line to size with the knife.
If your mower is equipped with a fuel shut-off device, it is usually located at the bottom of the fuel tank, where the fuel line connects to the tank.
What you need for a wet repair is a JB Weld Autoweld or SteelStik epoxy putty pen. Once the epoxy has hardened, it can withstand 300 degrees and 900 psi of pressure, making it perfect for your leaking fuel tank. This is the fastest way to keep expensive fuel in the tank, not on the asphalt.
A: When fully cured, JB Weld is completely resistant to water, gasoline and almost all petroleum products or automotive chemicals. For information on repairs with wet or submerged water or gasoline, see our JB Stik or Waterweld product information.
A: We do not recommend using Flex Seal Liquid® to seal a fuel tank or any other tank that comes in contact with other flammable liquids.
The carburetor float can be permanently locked in the open position so that gas can flow through the air filter and out of the mower. This is usually a sign of contaminated fuel. Cleaning the floats and carburetors and replacing or cleaning the fuel filter can help solve this problem.
Sometimes the fuel valve diaphragm wears out and allows fuel to flow to the carburetor when the unit is shut down, causing excess fuel to drain through the overflow pipe. Now let’s say it’s connected properly, fuel flows from the fuel tank into the floating cup.
A damaged polypropylene fuel tank cannot be repaired with epoxy or a plastic tank repair kit because gasoline will quickly dissolve the epoxy and the leak will recur. Polypropylene is a thermoplastic material, which means you can heat melt plastic and make a permanent repair in the polypropylene gas tank.
