What You'll Learn
Using a petroleum-based solvent to break down deposits
If your fuel tank is clogged with rust or sediment, you can use a petroleum-based solvent to break down the debris. Seafoam is a petroleum-based solvent that can be used to remove carbon deposits and gunk from inside engines and fuel systems. It can be added to the fuel tank to break down deposits in the fuel line.
To use Seafoam, fill your tank with gas and pour in a bottle of Seafoam. Do this for the next three tank fills. If your fuel filter is inline, change the filter as well. For every gallon of gas, use one-third of a can of Seafoam. Let the engine idle—there's no need to put any load on it. As the fuel pump pulls fuel from the tank to the engine, it will expose the crud in the lines to the Seafoam mixed with gasoline and start breaking it down, allowing the gasoline to flow better and letting you drive the car.
You can also use a high-quality fuel system cleaner to break down deposits and contaminants in the fuel system, including the fuel tank. Simply pour it into the gas tank and let the vehicle run so the cleaner can circulate through the system.
Other cleaning solutions are available that can tackle any grime and gunk buildup within the fuel tank. These can be left to sit for a couple of hours before the tank is rinsed with a pressure washer or a garden hose.

Using an air compressor to clear the blockage
Firstly, shut off the boiler or any relevant machinery connected to the fuel line. This is an essential safety measure to prevent any accidental activation during the unclogging process.
Next, locate the pump and use a suitable wrench to shut it off. In some cases, this may involve turning off a grease fitting or a similar component. It is important to identify the correct valve to avoid accidentally opening or closing the wrong one.
After turning off the pump, you should disconnect the fuel lines at the boiler. This will provide access to the fuel line that needs to be cleared. Be sure to have a bucket or a container ready to catch any fuel or debris that may come out during the process.
Now, you can attach your air compressor to the fuel line. Ensure that you have the correct adapters to interconnect the air compressor hose securely. It is crucial to preset the psi level on the air compressor's regulator to a safe amount, as too much pressure can damage the fuel line. Consult a professional or refer to the manufacturer's guidelines to determine the appropriate psi level for your specific fuel line.
Once the air compressor is connected and the psi is set, you can turn on the compressor and begin blowing air through the fuel line. Start from the tank end of the fuel line and work your way through. This should help dislodge any blockages and clear the line. Ensure that you are performing this step in a well-ventilated area to allow fumes to dissipate.
Finally, reassemble the components and bleed the fuel line to remove any trapped air. Refer to your machinery's user manual or seek advice from a professional for proper bleeding procedures.
While using an air compressor can be an effective way to unclog a fuel line, it is important to exercise caution and understand the risks involved. Always put safety first, and if you are unsure about any steps or feel uncomfortable performing the task, it is best to consult a qualified technician.

Cleaning the tank and adding additives
If your fuel tank is clogged, it is important to clean it and consider adding additives to prevent future clogs.
Start by inspecting the tank to determine the cause of the clog. If the clog is due to sludge or debris, you will need to clean the tank. Drain the tank completely and remove any visible sludge or debris. You can use a brush or a pressure washer to clean the inside of the tank. Be sure to dispose of the sludge and debris properly, as it may contain hazardous materials.
If the clog is due to rust, as is common in older tanks, you may need to use a rust remover or converter to treat the affected areas. You can also try using a carburetor cleaner or a product specifically designed to remove rust from fuel tanks. Fill the tank with the cleaner and let it sit for several days before flushing it out.
To prevent future clogs, you may want to consider adding a fuel additive to your tank. Fuel additives can help to clean and lubricate the fuel system, improve combustion, and prevent the buildup of sludge and varnish. There are two main types of fuel additives: fuel injector cleaners and solvent-type cleaners. Fuel injector cleaners, such as Techron Complete, focus on cleaning fuel injector deposits. Solvent-type cleaners, such as Berryman B-12, are designed to remove varnish and other soluble gunk from the entire system.
When choosing a fuel additive, be sure to read the labels carefully and select one that is compatible with your fuel type and engine. It is also important to follow the instructions on the package for proper usage and dosage.
Additionally, regular maintenance of your fuel tank and fuel lines can help prevent clogs. This includes checking for leaks, ensuring proper ventilation, and periodically cleaning or replacing fuel filters.

Using a Co2 Blowout tool
To use this method, start by disconnecting the oil line at the oil filter and its inlet at the oil tank. Attach the CO2 blowout gun to the oil line and send a blast of carbon dioxide backward through the oil supply line. This will push the blockage back into the oil tank. It is important to note that you should always use a waste container to carefully catch the debris and crud that comes out of the line.
While this method can be effective, it is important to exercise caution. CO2 cartridges can develop pressures in excess of 800 PSI, which can rupture copper oil lines. As such, it is recommended to use a hand push/pull pump or a small canister of compressed air with appropriate fittings instead of a CO2 blowout gun.
Additionally, it is crucial to determine the cause of the clog and address it to prevent future blockages. Some common causes of clogged fuel lines include water or ice entering the line in freezing climates, dirty tanks, bad fuel, and collapsed or pinched fuel lines.

Using a hand push/pull pump
To start, you will need to shut off the boiler and use a 3/8 wrench to shut off the pump. This will involve locating the grease fitting, which looks like a grease fitting, on the pump and turning it with the wrench. Next, disconnect the lines at the boiler and shut off the valve at the bottom of the tank. Keep the valve on the other tank open, especially if you suspect that tank is clogged.
Now, you can use the hand push/pull pump to clear the clog. Insert the pump into the fuel line and pump it up and down to force the fuel through the line. This action will help dislodge any blockages and push them out of the line. Ensure you are careful and deliberate with your movements to avoid causing any damage to the fuel line or the pump.
After you have cleared the clog, it is important to determine why the fuel line became clogged in the first place. This could be due to a pinhole in the supply tube, a bad fuel source, a dirty tank, a collapsed or pinched fuel line, or a lack of a filter at the tank. Addressing the root cause will help prevent future clogs and potential damage to your heating system.
