If you need to drain the fuel tank of your 2004 Ford Explorer, there are several methods you can try. One way is to remove the filler hose at the tank and then drain the gas by opening the check valve. You can also try removing the fuel filter and using a pump to remove the fuel, or disconnecting the line at the motor and using the tank pump. If you want to avoid cutting an access hole in the body of the vehicle, you can try removing the fuel pump relay and hot-wiring it, or unplugging the inertia switch and running battery power to the pump. Additionally, you can try using a siphon hose in the tank inlet, under or over the baffle. It is important to note that you don't need to drain the tank completely, and diluting the remaining fuel with fresh gasoline can be a solution.

What You'll Learn

Removing the filler hose at the tank
First, locate the filler tube under the vehicle. You will find a smaller tube that attaches to the filler tube up high. This smaller tube is the breather or vent that allows air to escape from the tank when gas is entering.
Next, get a large rectangular drain pan to catch the fuel. Remove the filler hose at the tank and place the drain pan underneath to catch the fuel.
Then, open the check valve to let the fuel flow out. You might need to use a special tool to press in the tabs on the fitting if it is difficult to remove. Alternatively, you can use a Ford/Chevy door handle removal tool that has been ground out to make a removal tool for the large fuel filler.
Finally, dilute the drained fuel with fresh gasoline. You don't need to drain the tank completely, and diluting it will ensure there are no problems.

Using a hand pump
To drain a 2004 Ford Explorer fuel tank using a hand pump, you can try the following methods:
Firstly, locate the filler tube, which is where you pump gas into the vehicle. You will see a smaller tube attached to it that connects to a rubber hose and then to the tank. This smaller tube is the breather or vent that allows air to escape when gas is entering the tank. Check this tube for any damage, bends, or kinks as this could be causing the slow fill issue.
If the tube is not damaged, you can try removing the filler hose at the tank and inserting a hand pump hose through the filler neck. This method was attempted by a user who reported that it worked to some extent, but they were unsure how much fuel was drained.
Another method is to remove the fuel filter and use a jumper wire to power the pump at the fuel pump relay under the hood. This will allow you to run the pump to drain the fuel.
Alternatively, you can try removing the fuel pump relay and hot-wiring it, or unplugging the inertia switch and running battery power to the pump.
If you do not want to cut access to the tank, you can try disconnecting the fuel line at the motor and using the tank pump to pump out the fuel.
Please note that some users have reported that draining the tank completely might not be necessary, and diluting the fuel with a tank of fresh gas may be sufficient.

Removing the fuel filter
Firstly, locate the fuel filter. It is usually found near the fuel tank or along the fuel line. Once you have located the fuel filter, place a drain pan or a container underneath it to catch any spilled fuel. You don't want to spill fuel all over your garage floor or the ground!
Next, you will need to disconnect the fuel lines that are attached to the fuel filter. Be very careful during this step as the fuel lines may still contain some fuel, and you don't want to spill any. There may be clamps or other fasteners holding the fuel lines in place, so make sure to have the appropriate tools on hand to remove them.
After the fuel lines are disconnected, carefully remove the fuel filter. Depending on your vehicle's configuration, there may be additional brackets or mounting hardware holding the fuel filter in place, so be sure to remove those as well.
At this point, the fuel filter should be removed, and you will have access to the fuel tank. You can now drain the fuel tank by using a hand pump or siphoning the fuel into an appropriate container. Remember always to take the proper safety precautions when working with fuel, and dispose of the drained fuel responsibly.
Additionally, some people have suggested alternative methods to remove the fuel filter. One suggestion is to use a Ford/Chevy door handle removal tool, which can be ground out to create a tool to remove the large fuel filler. Another option is to use a trans jack or m/c jack to lift the tank, as floor jacks can be unstable.

Disconnecting the line at the motor
To disconnect the line at the motor, you can start by removing the fuel filter. Then, disconnect the line at the motor and use the tank pump to pump out the fuel. It is important to note that you might need to turn the ignition on to run the pump.
Another way to achieve this is by removing the filler hose at the tank and then draining the gas by opening the check valve. This method will allow you to drain most of the fuel, except for a small amount, which can be diluted with fresh gasoline.
Additionally, you can try using a simple length of fuel line that slips over the male fitting on the fuel line. There is no need to clamp or lock it, as there is no significant pressure build-up when the hose ends into a gas can.
If you want to avoid cutting an access hole in the body of your Ford Explorer, you might consider removing the fuel filter and jumping the power at the fuel pump relay. This will allow the fuel pump to drain the tank for you.
It is worth noting that draining the fuel tank completely might not be necessary. Diluting the remaining fuel with a tank of fresh gas or using a FlexFuel model with E85 can effectively clean the tank and absorb any moisture.

Using a tank pump
To drain a 2004 Ford Explorer fuel tank using a tank pump, you can try the following methods:
Method 1:
- Remove the filler neck hose.
- Insert a drain hose connected to a fuel caddy with a pump to pump the fuel out of the tank.
Method 2:
- Remove the fuel filter or disconnect the fuel line at the motor.
- Use the tank pump to pump out the fuel.
Method 3:
- Pull the fuel filter or the fuel feed line from the engine.
- Run a hose from there into a gas can.
- Jumper the relay or run battery power (jumper box or long cables) back to the fuel pump power connector on the frame rail ahead of the tank.
Method 4:
- Remove the filler hose at the tank.
- Insert a hose connected to a hand pump through the filler hose and into the filler neck on the tank.
Method 5:
- Remove the fill tube to bypass the screen.
- Disconnect the line and pump into a car or gas can with a fuel pump.
It is important to note that you should use approved containers for receiving fuel, and these containers should be placed on the ground. Additionally, some users have reported difficulty in draining the tank completely, so you may need to dilute any remaining fuel with a tank of fresh gas.

Frequently asked questions
There are several ways to drain a 2004 Ford Explorer fuel tank. You can:
- Siphon through the filler neck using a piece of clear 3/8" OD tubing.
- Remove the filler hose at the tank and open the check valve.
- Remove the fuel filter and jumper the power at the fuel pump relay.
- Disconnect the line at the motor and use the tank pump to pump the fuel out.
- Drive until you run out of gas.
There are several reasons you might need to drain your fuel tank, including if you've put the wrong type of fuel in your car, or if your fuel pump isn't working.
If your fuel pump isn't working, you might experience problems filling up your tank, such as the pump kicking off after a few seconds.
A fuel pump is part of the fuel pump assembly inside the gas tank and is necessary for filling up your tank with gas.
You don't need to drain 100% of the fuel. As long as you dilute it with a tank full of fresh gas, it shouldn't be a problem.
