I received my new Sinix backpack leaf blower a few days after I ordered it, but after I put everything together along with oil and gas. The leaf blower wouldn’t start. I smelled gas and noticed that gas was leaking near the gas tank. The gas return fuel line wasn't in the gas tank because it was cut too short. I reached out to customer service on two occasions and I didn’t get a response to my request to repair the gas line or replace the leaf blower. I repaired the gas line myself and the leaf blower is working great.
