Wet-dry vacs can be used to empty fuel tanks
Some people have suggested using a wet-dry vac to empty fuel tanks, particularly in situations where the tank is difficult to access or remove. For example, one person suggested using a wet-dry vac to clean out their fuel tank after finding fibrous strands in the fuel shutoff valve. Another person used a wet-dry vac to clean marbles out of a dozer's fuel tank.
However, there are significant risks associated with using a wet-dry vac for this purpose. The primary concern is the potential for the fuel to ignite or explode. Fuel, when atomized and mixed with air, can be highly flammable. If the fuel comes into contact with a spark or flame, it could result in a fire or explosion. There have been reported incidents of fires and explosions occurring when individuals have attempted to use a wet-dry vac to clean fuel tanks.
Additionally, some wet-dry vacs have filters that are not suitable for use with liquids. Paper filters, in particular, can become waterlogged and impede airflow. Therefore, it is important to check the manufacturer's instructions and ensure that the wet-dry vac is equipped to handle liquids before attempting to use it for this purpose.
If you decide to use a wet-dry vac to empty a fuel tank, extreme caution must be exercised. It is recommended to have a fire extinguisher readily available in case of ignition. Some people also suggest using a hose to put out any potential flames.
Overall, while it is technically possible to use a wet-dry vac to empty a fuel tank, it is not advisable due to the serious safety hazards involved. Alternative methods, such as using an oil extractor pump or siphon, are generally recommended as safer options.

The risk of fire or explosion is high
Using a wet-dry vacuum to clean up diesel fuel is highly dangerous and can lead to fires and explosions. The risk of fire or explosion is high due to several factors:
Firstly, a vacuum sucks in air at high velocity, atomizing the fuel into the air stream. This fine mist of fuel can easily ignite when exposed to a spark or flame, leading to a potential explosion. Vacuums with electric motors can create sparks, especially if they come into contact with metallic objects or surfaces. Even a small spark could ignite the atomized fuel, resulting in a fire or explosion.
Secondly, diesel fuel is flammable and can produce flammable vapors. When diesel vapors mix with air, they can form an explosive mixture. The act of vacuuming can increase the risk of ignition by providing an ignition source or creating a spark. Additionally, the vacuum's motor can generate heat, which could potentially ignite the diesel fuel or vapors.
Furthermore, the vacuum hose itself can pose a hazard. If the hose comes into contact with a spark or flame, it could melt or burn, allowing the fuel to escape and potentially causing a fire or explosion. The user may also be at risk if they are holding the hose when this occurs.
The consequences of a fire or explosion can be devastating, as illustrated by an incident reported by the Albuquerque Fire Department. In this case, a man using a vacuum cleaner to suck up gasoline was burned, and his house was damaged in the resulting explosion.
Therefore, it is highly advisable to avoid using a wet-dry vacuum for cleaning up diesel fuel. Alternative methods, such as using oil extractors or absorbent materials, are safer options that do not carry the same risk of fire or explosion. While it may be tempting to use a vacuum for convenience or ease, the potential consequences far outweigh the benefits.

An alternative is to use an oil extractor pump
Using a wet-dry vacuum to pick up diesel fuel is not recommended due to the risk of fire and explosion. An alternative is to use an oil extractor pump, a relatively simple device consisting of a 12v motor with a pump attached and some electrical leads. This method is much safer and more convenient than a vacuum cleaner.
An oil extractor pump is a siphon pump that fits into the dipstick opening in the crankcase. It creates a vacuum to pull the oil out and many models also have a reservoir to hold the oil. This reservoir typically holds six to eight quarts, making it suitable for most light-duty trucks and passenger vehicles.
There are two main types of oil extractor pumps: manual and electric. Manual pumps are the least expensive option and may be similar to a bicycle pump or a syringe plunger. Electric pumps, on the other hand, are more convenient as they do all the work for you. They usually have a 12-volt plug that inserts into the vehicle's auxiliary power outlet or alligator clips that connect directly to the battery.
Using an oil extractor pump has several benefits. Firstly, it eliminates the need to crawl under the car to reach the drain plug, avoiding potential mess and discomfort. Secondly, it simplifies the process of changing your own oil, saving you time and money.
However, it's worth noting that some oil extractor pumps can be slow. For example, it took one user 20 minutes to extract four quarts of diesel using an extractor pump. Additionally, the pump can get quite hot during the extraction process. Therefore, it is important to warm up the oil before using the pump to speed up the process and prevent overheating.

A vacuum with a metal enclosure will spew fire
Using a vacuum to clean up diesel fuel is not recommended due to the risk of fire and explosion. While diesel fuel does not readily ignite, atomizing it and running it through an electric motor can create a flamethrower effect. In one instance, a vacuum with a metal enclosure was used to clean up spilled solvent, and it began spewing fire. The vacuum did not catch on fire itself, but the person operating it could have been seriously injured.
Vacuums can create sparks that can ignite fuel vapors, leading to an explosion. In 2007, a man in Albuquerque was burned and his house was damaged when he used a vacuum cleaner to suck gasoline out of a vehicle and the fuel exploded. This is not an isolated incident, as others have also reported fires and explosions when using vacuums to clean up fuel.
Even if the vacuum is capable of sucking up the diesel fuel, it is not worth risking your safety. It is much safer to use alternative methods to clean up diesel spills, such as oil extractors, absorbent pads, or dry ice to displace vapors. Taking the necessary precautions to avoid fires and explosions is crucial when dealing with flammable substances like diesel fuel.
While some people may argue that having a fire extinguisher on hand is enough to mitigate the risk, it is still a dangerous practice. The potential consequences of a fire or explosion far outweigh the convenience of using a vacuum for fuel cleanup. It is always better to prioritize safety and choose a different method that does not involve creating a potential ignition source near flammable liquids.
To conclude, using a vacuum with a metal enclosure or any other type of vacuum to clean up diesel fuel is highly dangerous and can lead to fires and explosions. Alternative methods such as oil extractors or absorbent materials are safer options that do not pose the same level of risk. By choosing these alternatives, you can effectively clean up diesel spills while minimizing the chances of an accident occurring.

A fire extinguisher should be kept close by
Wet-dry vacs are versatile and can be used to clean up messes that ordinary household vacuums cannot. However, using a wet-dry vac to pick up diesel fuel is not recommended due to the risk of fire or explosion. Diesel is a flammable liquid, and when atomized, it can easily ignite, especially if there is an electrical spark.
It is also crucial to know how to use a fire extinguisher properly. The PASS technique is a commonly taught method: Pull the pin, Aim the nozzle at the base of the fire, Squeeze the handle to release the extinguishing agent, and Sweep from side to side at the base of the fire until it is out. If there is any doubt about tackling the fire, it is best to evacuate the area immediately.
Additionally, it is important to address the cause of the fire and remove the fuel source to prevent re-ignition. This may involve stopping the flow of diesel or removing the wet-dry vac if it is the source of the sparks. While having a fire extinguisher close by is essential, taking preventive measures to reduce the risk of fire is equally important. This includes being cautious when dealing with flammable liquids and avoiding creating conditions that could lead to a fire.
In summary, while a wet-dry vac can be used to pick up diesel fuel, it is a hazardous operation due to the risk of fire and explosion. Keeping a fire extinguisher close by is crucial for fire safety and should be accompanied by knowledge of how to use it effectively. Taking preventive measures, addressing the cause of the fire, and removing the fuel source are also vital components of fire safety.
