Ford truck owners may want to inspect their fuel tanks for debris, rust, or sludge. While some recommend removing the tank for a thorough inspection and cleaning, this can be a challenging task. As an alternative, you can try draining the tank and using a pressure washer to remove debris and rust. Additionally, a cleaning solution can be applied and left for a few hours before rinsing and drying the tank. For serious issues, such as varnish or sticky sludge, a fuel tank cleaner combined with vacuum extraction may be necessary. It is recommended to clean your fuel tank every 5 years or 50,000 miles, whichever comes first, to prevent engine problems.

What You'll Learn
Drain the tank
Draining the tank is a temporary solution to the problem of rust and sediment build-up. To properly clean the tank, it should be removed and cleaned and sealed. However, if you wish to drain the tank, there are a few methods.
One method is to use a siphon. Get an 8-10 foot length of hose and feed it through the fuel filler tube to the tank. Ensure that the hose is long enough so that one end is low in the tank, and the other end is higher than the gas filler neck. Place your thumb over the end that is higher and stick the other end into a gas can or bucket that is lower than the bottom of the tank. You should see the gas flow immediately, and it will drain to the level of the can or bucket.
Another method is to use a pump. You can use a manual transfer pump into the tank fill port after removing the fill hose, or you can use a pump to suck the fuel out into a bucket.
Alternatively, you can try using an air compressor. Shove a hose down the fill tube, stuff a rag around it, and insert the end of a blow gun from an air compressor. Seal off both and the pressure from the compressor will force the fuel out of the tank via the hose.
Finally, you can try to jack up the car and drill a hole in the bottom of the tank, placing a funnel underneath to catch the fuel.

Use a pressure washer
To look inside your Ford fuel tank without removing it, you can use a pressure washer. This method is useful if you want to clean the inside of your tank and inspect it for any remaining debris or rust.
First, jack up your car and disconnect the tank's screws and straps. Then, drain the tank by suctioning out the gas or turning the tank upside down over a container. Next, mix dish detergent and hot water, put it in your tank, and let it sit for 24 hours. This process will help to remove any gasoline smell and degrease the tank. Finally, empty the detergent-water solution and use a pressure washer to spray down the inside of the tank.
The pressure washer will help dislodge any remaining dirt, debris, and small flakes of rust. It will also rinse out gasoline sediment. You may need to point the sprayer at different angles to effectively remove light rust and other sediment buildup. Additionally, if there is substantial rust or grime in the tank, you may need to use commercial cleaning solutions specifically designed to remove rust.
Using a pressure washer is an effective way to clean and inspect your Ford fuel tank without removing it. This method can save you time and effort, as you won't need to completely disassemble the tank. However, it's important to follow safety precautions and properly dispose of any fluids drained from the tank.

Degrease the tank
To degrease a fuel tank, the first step is to disconnect the tank from the vehicle. This involves unstrapping the tank and unscrewing any screws or bolts that secure it in place. For a lawnmower or similar equipment, the fuel line and spark plugs must be removed, while for a motorcycle, the petcock, gas cap, and all attached hoses must be detached.
Once the tank is disconnected, seal the fuel line to prevent residual gasoline, dirt, or other objects from entering and potentially damaging the engine. This can be done by clamping the line near the carburetor, separating it from the carburetor, and positioning it over a bucket.
Next, remove the tank from the vehicle. At this point, you have the option to pressure wash the inside of the tank to dislodge dirt, debris, and rust. If the tank has substantial rust or grime, you may need to use a commercial cleaning solution to break down the rust before rinsing and removing the debris.
To degrease the tank, you can use a product like Purple Power Degreaser or a mixture of light soap and water. If the tank is clean but rusty, filling it with white vinegar and nuts or a chain and boiling water and detergent can help remove rust. Seal the openings of the tank and, if possible, use a cement mixer or strap the tank to a tractor tire to agitate the contents and scrape away the gunk.
After degreasing, rinse the tank several times to ensure all suds or soap residue is removed. To do this, empty the tank and refill it with clean water, rinsing until there are no bubbles or foam present. Turn the tank upside down to facilitate better draining and allow it to air dry completely before reattaching it to the vehicle.
If the tank has severe corrosion or rust, it may be more advisable to replace it with a new one rather than attempting to clean and refurbish it.

Apply a cleaning solution
To apply a cleaning solution to your Ford fuel tank without removing it, you have several options.
Firstly, you can use a commercial fuel tank cleaner. These are available for both diesel and petrol fuel tanks. Pour the cleaner into the tank, swirl it around to ensure it covers all interior surfaces, and then drain it into a separate container. Allow the tank to air dry completely to prevent moisture from contaminating the fuel.
Alternatively, you can use a mixture of cleansers, stabilizers, lubricants, or performance boosters. These treatments help the engine run smoothly, preserve fuel quality during storage, and improve vehicle performance and mileage.
If you're dealing with rust, several products can help. One option is to use a chelating agent, such as Evaporust or MetalRescue, which chemically reduces the rust back to metal. You can also try an electrolysis method, which involves filling the tank with water and washing soda and hooking it up to a power source. Another option is to use RedKote, which seals leaky seams and pinholes.
For a more natural approach, white or apple cider vinegar can be used to clean fuel tanks. Fill the tank 99% full and let it sit for 2-7 days, inspecting every 24 hours. Drain, rinse, and inspect the tank, and if needed, put the vinegar back in for another day or two.
Remember, it's important to ensure that the tank is thoroughly dry, both inside and outside, before refilling it with fuel.

Rinse and dry
Once you have drained the tank and applied a cleaning solution, you will need to rinse the tank with water. You can use a pressure washer or a garden hose for this step. The key is to remove as much grime and dirt as possible. Don't worry if some of the cleaning solution remains, as this will get sent to the fuel injectors and burned off with the rest of the fuel.
After rinsing, it is important to leave the tank to dry for at least 24 hours, and preferably 48 hours, to ensure it is completely dry. If you don't leave the tank to dry for long enough, you may experience problems with acceleration or changes in speed. To speed up the drying process, you can introduce compressed air into the tank to eliminate excess moisture.
Before reinstalling the tank, make sure there is no smell of gasoline. This will indicate that the tank is clean and dry.
Finally, add a fuel stabilizer to prevent corrosion and extend the life of the tank.
Safety Precautions:
- Wear appropriate Personal Protective Equipment (PPE), including gloves, goggles, and a respirator, to protect against fuel vapors and fumes.
- Ensure the area is well-ventilated to prevent the buildup of hazardous fumes.
- Avoid using tools or equipment that could create sparks, as fuel vapors are highly flammable.
- Have a fire extinguisher nearby and know how to use it in case of an emergency.
- Continuously monitor the cleaning process for any signs of leaks, spills, or other hazards.
