The Complete Guide on Diesel Fuel Tank Maintenance

In 2019, about 1.1 billion barrels of diesel fuel were used. 

If you are going to be one of the suppliers of diesel fuel, you’ll need somewhere to store it, which will most likely be a diesel fuel tank.

However, a diesel fuel tank needs proper maintenance and care in order to work correctly and last a long time. But how do you maintain it? Keep reading to find out all of the proper steps to take!

Power Wash the Tank

When it comes time to do your routine maintenance of the tank, you should make sure that you power wash it. The outside of the tank will need to be accessible and clean so that it doesn’t contaminate anything.

This is why you should power wash it. You can use a regular fan tip to clean and wash all of the accessible portions of it. If you need access to the roof of the tank, you can bend it a little bit to try and reach it. 

However, once you’re done with that, you’ll have to clean the harder areas to reach. You might want to get a nozzle that sprays ina ll kinds of different directions to clean everything. There are also different manufacturers that make tips specifically to clean out the tank. 

When you’re rinsing all the dirt and fuel off, you’ll need to make sure it’s all drained properly into a lower area. You’ll need to pump it out while you’re power washing it. 

Make sure when you’re power washing it that you don’t have it on the highest setting and that you don’t point it at anyone because it can injure them.

Change Out the Fuel

How long you can store the fuel in there will depend on all kinds of different factors. You need to make sure it’s cool and dry. If you’re storing it under these conditions, it could last anywhere from six to twelve months.

If you want it to last longer than twelve months, you’ll need to add stabilizers to it. This will help to reduce the frequency that you have to do routine maintenance on the tank. 

Burn the Fuel

Before you clean the tank, you should burn down the fuel first, especially if it’s been over twelve months and has gone bad. You can pump all of the fuel out of the tank; however, it’s a lot more work. 

You should do this before it becomes too big of an issue, so make sure that you regularly maintain and clean it. 

Do a Thorough Cleaning

Some people recommend completely emptying out the fuel and cleaning it every ten years. However, you may need to do this more depending on where your tank is located. 

Once you’ve emptied the tank, you’ll have to drop the tank. If you aren’t sure how to do that, you can always refer to your service manual which should tell you how to do it.

Next, you can use a brush to clean the area where you removed the pump.  Once you’ve used the brush, you can remove the fuel pump. Don’t let any debris from removing it falls into the tank, however. 

You can then point a hose into the tank and use hot water to clean it all out. You may want to also use a mild detergent to get rid of really difficult stains or issues. 

Once you’ve sprayed everything, you can get all of the dirty water out into a pan, and make sure any liquid you got out of it is contained. 

Once all of the water is out of the tank, you can wipe it with a washcloth that doesn’t have any lint on it. To fully dry it, you might want to use compressed air to dry it all out. 

You should then investigate to see if there are any damages to the tank. You should get those taken care of now before you fill it back up with fuel.

If there are no damages, you can let it fully sit and dry for thirty minutes, and then you can fill it back up with fuel. To learn more about how to clean a fuel tank, click here to read more.

Why It’s Important

You might be wondering if it’s worth it or necessary to clean out your diesel fuel tank, but it definitely is. It will help it last longer, and it will help avoid it getting damaged. This will save you money and time in the long haul. 

So to make sure it’s all taken care of, make sure you clean it, service it routinely and make sure it’s ready for the cold winter months as well. 

If you need to replace something because it’s broken or worn down, make sure you find a quality piece to replace it with. 

Whenever you’re in doubt, make sure that you hire a technician to come out and take a look at it.
