How Much Does It Cost To Drain A Fuel Tank


When your car needs to be towed, you will want to make sure that it is drained of all its fuel before they take it away. This is because if there is still gas in the tank, then it cannot be emptied properly or completely.

If someone does not drain the vehicle correctly, then some of the gasoline may eventually leak out, which can cause poisoning or even death to the surrounding area.

This article will go into more detail about how to drain an automobile’s fuel tank safely. It will also talk about the costs related to this job so that you know what to expect before you do it.

I have included pictures and videos below to help illustrate these points.

Run a diagnostic test

The next thing you should do is perform a quick inspection to see if there are any warning signs that your vehicle may be having an issue with fuel.

If you notice smoke coming out of the car or flames, WARNING! This could mean danger for yourself and others around you.

It’s best to leave this situation alone unless you have some knowledge about cars. Don’t try to start the engine yourself, it can hurt much more than help.

Instead, find someone who knows how to fix vehicles so they can tell you what needs done next. You don’t want to waste money by buying something that doesn’t work correctly when you can easily prevent this from happening again.

Many things contribute to a vehicle running out of gas, but one of the most common causes is a clogged fuel filter. If you notice white powdery deposits in your tank, then you need to change the filter.

But before you get too excited, make sure you know what kind of fuel system your vehicle has first.

Do a visual inspection

The next thing you should do is perform a quick visual inspection of your vehicle. You want to make sure there are no fluids leaking out anywhere on or around the car.

If you find any fluid, stop what you’re doing and try to determine where it’s coming from. See if you can locate the source by looking at the car in different lights and observing the area more closely.

Connect a tool to the tank

The next step is to connect your drain tool to the fuel tank!

Mostly made of plastic, these tools have a tube that you insert into the hole in the car’s body where the fuel tank connects. Some require you to use a pin to attach it, while others have suction cups that stick onto the wall of the tank.

The cost for this depends on who does it for you- mechanic or self. If you do it yourself, then buying a cheap one is acceptable, but make sure it works by trying to find a free sample from another source or taking it out for a few minutes to see if it works.

Remove the cap

The next thing you will need to do is remove the fuel line connector or gas pipe clamp that holds the hose in place. You can either pull it out, cut it off, or push it away from the tank.

Once this is done, you can now pull the hose straight up. This way, you don’t have to hold onto it with your hands anymore! Once it’s fully pulled up, test the nozzle to make sure there’s no fluid coming out. If there is, reconnect the tubing and try again at a different angle or position.

This whole process should take about 30 seconds to 1 minute per car. And although some cars have very easy to access fuel tanks, others may require more care and attention to detail.

Look for leaks

The next thing you should do is look for any leakage coming from your car’s fuel system. You can use a bright light to help you spot fluid seeping out anywhere around the engine.

If you notice liquid escaping through cracks or seams in the tank, it may be time to start looking closer at how to drain your vehicle’s fuel tank.

You will want to make sure everything is cleaned properly before filling up again, however, so as not to risk having an accident due to lack of fuel.

Sadly, some cars are more difficult to work with than others. Some have tanks that leak heavily even after being checked thoroughly, which makes this process slightly more expensive.

Use a siphoning tool

Many vehicle owners do not realize that it is very expensive to drain your car’s fuel tank. This can easily cost over $1,000!

Since most cars have at least a half-gallon (one liter) of fuel in them when they are manufactured, there are many ways to get this done. The cheapest way is to buy a cheap bottle of soda or water at your local store and use those as fuels, but this will almost always produce smoke and/or flames.

More professional methods include using special tools designed for draining fuel tanks. These tools are usually sold online or through auto parts stores, and can be quite expensive depending on how much you want to spend.

Warning! Never pull out any part of the engine yourself unless you know what you are doing. Doing so may hurt the engine or cause an explosion.

Use a drain plug

The best way to begin draining your car’s fuel tank is by using a drain tool or device that has a built-in plastic plug. This helps prevent fluid from escaping due to gravity.

Many tools have this feature, but not all of them are cheap! If you run across one that does not, feel free to look up how to make your own. Luckily, you can usually find easy ways to do so online and through helpful friends or mechanics.

The first thing to do is use a source of light to see if there is any fluid leaking out of the hose at the end of the tap.

Run the engine to purge the tank

When your car is empty, it needs to be cleared of all of its fluid components. This includes gasoline, brake fluids, coolant, and oil!

Most cars have a small tube that connects to the intake manifold or combustion chamber. This tube is used to remove any residual fuel from the vehicle. If you never turn off your car, then this process happens very quickly!

However, if your car was just drained of liquid then this quick draining may not work as well. Because there’s no longer anything for the leftover fuel to combine with, it will remain in the pipe until you start the engine.

This can cause damage to the engine because the remaining gas could corrode metal parts or even explode due to excessive heat.
