Updated February 21, 2017

Accidents and constant use can cause the engine in your Briggs & Stratton lawnmower to get a leak. This poses a threat of possible fire on the engine. The gas tanks on Briggs & Stratton engines are either made of metal or plastic. Over time, the metal gas tanks can rust out and the plastic ones can become brittle. In these instances, you will have to remove the gas tank from the Briggs & Stratton engine and replace it.

Locate the gas line running from the base of the Briggs & Stratton engines gas tank to the carburettor.

Squeeze the clamp holding the end of the rubber hose to the base of the gas tank with pliers. Slide the clamp off the gas line.

Pull the gas line off with your hand and point it in the bucket to catch old gas.

Unscrew the two bolts holding the base bracket on the gas tank to the Briggs & Stratton engine frame. Use the proper sized socket to remove the bolts.

Pull the gas tank off the Briggs & Stratton engine.
