Using a pressure washer is a great way to tackle tough cleaning tasks, but if you let it sit unused for an extended period of time, the gas inside can go bad. Old, stale gas can clog up the fuel system and make it difficult for your pressure washer to start or run smoothly. To keep your pressure washer in top shape, it’s important to drain the old gas and replace it with fresh fuel.

Draining old gas from a pressure washer is a fairly simple process that can be done in just a few steps. First, you’ll want to locate the gas tank and fuel shutoff valve, which are typically located near the engine. Before you begin, it’s important to take safety precautions by wearing protective gloves and eyewear.

Once you’ve located the gas tank and shutoff valve, the next step is to turn off the fuel shutoff valve. This will prevent any fuel from flowing into the engine while you’re working on draining the old gas. With the valve closed, you can now remove the fuel cap to access the gas tank.

To drain the old gas, you can either carefully tilt the pressure washer to pour the gas out of the tank, or you can use a siphon pump to extract the fuel. Be sure to have a container ready to catch the old gas. Once all the old gas has been drained, it’s important to dispose of it properly according to local regulations.

After the old gas has been drained, it’s time to add fresh fuel to the gas tank. It’s recommended to use fresh, unleaded gasoline with the appropriate octane rating for your pressure washer. Fill the tank to the appropriate level as indicated by the manufacturer’s instructions. Finally, replace the fuel cap and open the fuel shutoff valve. Your pressure washer should now be ready to start and run smoothly with its new fuel.
