Small Engines (Lawn Mowers, etc.): part number or where to buy part, briggs stratton engine, briggs stratton

Question
Hello,
I have an old Murray 20" 3.5hp Classic lawn mower with a cracked metal gas tank. It has a Briggs & Stratton engine(family TBS158U1G1RA:EM displacement 148cc. Model 9V). I would like to know the part number for the gas tank and if possible where to purchase replacement parts from. Thanks in advance.

Answer
Hi Sandy,

I am sorry to say it appears you gave me the Emissions label off the engine.  Look above the spark plug or stamped by the muffler and you will see a model type and code number.  It will look something like this:  MODEL 92902 TYPE 0123-01 CODE 780331071

Please also tell me where u are from and I can direct you where to buy part
