Draining Fuel From Your Generac Pressure Washer: Step-By-Step Guide

Draining the fuel from a Generac pressure washer is a straightforward process that can be done in several ways. The most common method involves using a siphon hose to pump out the fuel from the tank. This is done by placing one end of the hose inside the tank, ensuring it reaches the bottom, and then clamping the hose in place. A pinch clip can be used to control the flow of fuel, and a bulb valve can be attached to the other end of the hose to help pump out the fuel. Other methods include using the remaining gas in the tank by running the engine until it is empty, tilting the pressure washer to drain the fuel, or disconnecting and draining the fuel line. It is important to drain the fuel properly to avoid internal and external damage to the device, and to prevent issues with gum deposits in the carburetor, which can harm the engine over time.

Using a siphon hose

Step 1: Prepare the Pressure Washer

Place your Generac pressure washer on a flat, level surface to ensure stability during the fuel drainage process. This will prevent any accidental spills or damage to your machine. Before beginning, it is crucial to disconnect the spark plug connection to avoid any potential hazards.

Step 2: Prepare the Containers

Place an empty container near the machine where you intend to collect the drained fuel. Remove the caps from both the fuel tank and the empty container. Keep them safely aside to avoid any confusion or misplacement.

Step 3: Insert the Siphon Hose

Obtain a siphon hose kit, which typically includes a hose with a brass nozzle at one end. Insert the brass nozzle end of the hose into the fuel tank of your Generac pressure washer. Ensure that the hose reaches the bottom of the tank to allow for complete drainage. Secure the hose to the opening of the fuel tank using a clamp, tie wrap, or duct tape. This will prevent the hose from moving or sliding out during the process.

Step 4: Install the Pinch Clip

On the opposite end of the hose, slide the pinch clip onto it. The pinch clip is an essential component as it allows you to control the flow of fuel. If you only need to drain a specific amount of fuel or change the fuel container during the process, you can simply pinch the clip to stop the fuel flow.

Step 5: Connect the Bulb Valve

The bulb valve is another crucial component in the siphon hose kit. Connect the bulb valve to the end of the hose without the brass nozzle. Locate the arrow on the bulb valve, which indicates the direction of the fuel flow. Ensure that you connect the hose to the end from which the arrow is pointing away.

Step 6: Pump the Fuel Out

Start pumping the bulb valve to draw the fuel from the tank. Continue pumping until the fuel reaches the point on the hose where the pinch clip is attached. Once the fuel reaches this point, pinch the clip to stop the flow temporarily. Then, carefully remove the bulb valve and pour the drained fuel into the empty container. Ensure that your Generac pressure washer is placed at a higher altitude than the container to facilitate easy drainage.

Additional Tips:

• It is important to handle fuel with care and avoid any spills.
• Always store drained fuel in a safe and properly labelled container in a well-ventilated area, such as a garage or shed.
• Remember to reconnect the spark plug and securely tighten the fuel cap after completing the fuel drainage process.

Draining the fuel by disconnecting the fuel line

Draining the fuel from a Generac pressure washer by disconnecting the fuel line can be done in a few steps. Firstly, you will need a fuel line clamper, a pair of pliers, and a fuel storage container. Locate the fuel tank and remove the engine housing if necessary. Find the tube or pipe going from the fuel tank's side to the carburetor. This is the fuel line.

To avoid fuel spillage, the next step is to clamp the fuel line. This will only work if the fuel line is a flexible tube. Take the pair of pliers and disconnect the fuel line. The most accessible location to do this is usually on the carburetor's side, but the fuel tank's side will also work. Ensure your pressure washer is placed at a higher altitude than the fuel container to allow the fuel to drain quickly. Using a funnel can make this process easier. Once all the fuel is drained, reattach the fuel line.

Using the remaining gas

If you only have a small amount of gas left in your Generac pressure washer, you can simply use the machine until it runs out of fuel. This is the easiest method, but it is not environmentally friendly if there is a significant amount of gas remaining.

If you are planning to store your Generac pressure washer for the winter, it is recommended to drain the gas. This can be done by letting the machine run out of fuel, or by using one of the other methods outlined below.

Another option for using the remaining gas is to tilt the pressure washer and let the fuel drain from the fill cap. This method is best performed by two people and is limited to pressure washers that can be tilted easily. Before tilting the machine, disconnect the spark plug wire to prevent the engine from starting accidentally. Also, ensure that the air filter assembly points upward when tilting the washer to prevent engine oil from flowing into the fuel tank. Place a plastic container and a funnel under the fuel cap to catch the fuel, then open the fuel cap and allow the fuel to drain into the container. Once the fuel has been drained, dispose of it properly and close the fuel cap. Finally, reconnect the spark plug wire.

If your Generac pressure washer has a carburetor with a dedicated drain screw, you can use this to drain the remaining gas. Simply locate the drain screw, usually found on the front of the carburetor, and unscrew it. Collect the drained fuel in a container. Note that not all drain screws on a carburetor also drain the gas from the tank, so you may need to use another method to completely empty the tank.

Tilting the pressure washer

Step 1: Tilt the pressure washer in the correct direction

Before tilting, ensure that the spark plug wire is disconnected so that there is no risk of the engine starting accidentally. Also, make sure that the air filter assembly points upward when tilting the washer. This step ensures the engine oil does not flow into the fuel tank.

Step 2: Use a container and funnel

Arrange a plastic container and a funnel to catch the fuel and place them under the fuel cap. Open the fuel cap and allow the fuel to drain entirely into the container.

Step 3: Close the fuel cap

Once the fuel has been drained, dispose of the fuel and close the fuel cap. Reconnect the spark plug wire.

Using a drain screw

Draining the fuel from your Generac pressure washer using a drain screw is a straightforward process. Here is a detailed guide on how to do it:

Step 1: Locate the Drain Screw

The first step is to find the drain screw on your pressure washer's carburetor. It is usually located at the front of the carburetor. Once you have located the drain screw, you can proceed to the next step.

Step 2: Prepare for Fuel Draining

Before you begin draining the fuel, it is important to take some safety precautions. Place your pressure washer on a flat and stable surface to prevent accidental spills or damage to the machine. Also, remove the spark plug connection to avoid any unwanted accidents. Now, place an empty fuel container near the machine to collect the drained fuel.

Step 3: Unscrew the Drain Screw

Using a suitable screwdriver, carefully unscrew the drain screw. Loosen the screw just enough so that the fuel starts pouring out of the valve. Be careful not to strip the screw head or cross-thread the screw. Have a paper towel or rag ready to catch any initial drips of fuel.

Step 4: Drain the Fuel

Once the drain screw is loosened, you can begin draining the fuel. Place a fuel-compatible container under the carburetor to collect the fuel. Depending on the size of your carburetor, the amount of fuel drained will vary. For smaller carburetors, you can use a funnel or kitchen paper to collect the fuel and minimize spillage. For larger carburetors, you may need to use a flexible tube attached to the drain to direct the fuel flow into the container. Work quickly to catch all the fuel and avoid spills.

Step 5: Re-tighten the Drain Screw

After you have drained the fuel, re-tighten the drain screw securely. Make sure it is tightened properly to prevent any leaks. Clean up any spilled fuel with an appropriate absorbent material, such as paper towels or rags.

Step 6: Store the Drained Fuel

Properly store the drained fuel in a safe location, such as your garage or shed. Ensure that the fuel is kept away from open flames, sparks, or other sources of ignition. Always label the container with the date and contents to avoid confusion.

Remember to perform regular maintenance on your Generac pressure washer to keep it in optimal condition. Draining the fuel using the drain screw method is an essential part of maintaining your machine and ensuring its longevity.
