Gas tank leaks
Hi everyone, I have a Sears power washer powered by a Briggs 4.5HP gas motor. I hadn't operated it for the past 7 or 8 years but I need it now. Yesterday I took from the spot where it was stored, checked the oil and gas tank. The oil was full but the gas tank was empty. I figured, what the heck, I'll put some gas in it and see what happens. Well, as soon as put some in, I noticed the fuel line was full of cracks and leaking like a sun of a gun. And, I also noticed that there was gas coming from the gas tank somewhere. But, I tried to start it anyway. It fired right up on the second pull. Surprised the heck out of me. However, I need a way of fixing the gas tank. The leak is at the seam where the 2 pieces come together. Does anyone know what I can use to apply to the seam to plug the leak that can handle gasoline? The gas line I can get anywhere. Thanks, Roger

Joe is giving a suggestion for a metal tank... I assumed it is a plastic tank. Since you didn't give a model to look it up... which is it? Plastic or metal?

It's plastic. They are bad about leaking at the seams and it requires tank replacement. You'll never get it to stop by trying to fix it.

Sorry. I should have included that it is a plastic tank and I was afraid the only solution to the leak is replacement of it. I'll go to Sears parts direct and see what kind of money they want for a plastic tank.
Thanks for the replies, everyone. I appreciate you taking the time to answer.

It's hard to believe they want nearly $40.00 for a plastic fuel tank and fuel cap.
Perhaps you folks can find it cheaper somewhere?

Model number off engine will be the big helper here or if you have the part number. Type in Briggs and Stratton Gas tank on e-bay and it will bring it up. Model number on engine will be on recoil housing on a little tap of metal just above muffler, if memory servers me correct.
