Hey there! As a fuel tank trailer supplier, I often get asked about how to store these trailers when they're not in use. It's a crucial question because proper storage can significantly extend the lifespan of your trailer and keep it in top - notch condition for the next time it's needed.
First off, let's talk about the pre - storage cleaning process. Cleaning the fuel tank trailer thoroughly should be your number one priority. This isn't a quick hose - down job; it requires a more in - depth approach. Start by emptying the tank completely. Remaining fuel can lead to corrosion over time, especially if it contains any impurities. Once the tank is empty, use a high - pressure washer to clean the exterior of the trailer. Pay special attention to areas that are more prone to dirt and grime buildup, like the wheels, undercarriage, and the connections between different parts of the trailer.
The interior of the tank also needs careful cleaning. You can use a specialized tank cleaner that's designed to break down any residue left on the tank walls. After cleaning, rinse the tank multiple times with clean water to ensure all the cleaning agents are removed. Leaving behind cleaning chemicals can also cause damage to the tank.
Next up is inspections. Before you store the fuel tank trailer, give it a comprehensive inspection. Check the tires for any signs of wear or damage. Low tire pressure during storage can lead to flat - spotting, which means the tires develop a flat area on the part that's in contact with the ground. Inflate the tires to the recommended pressure, and if you notice any cuts, bulges, or uneven wear, it's a good idea to replace the tires.
Inspect the brakes as well. Make sure the brake pads have enough material left, and there are no signs of leakage in the brake lines. If you find any issues with the brakes, it's best to get them fixed before storage. You should also check the lights, electrical connections, and the hitch mechanism. Faulty lights can be a safety hazard when you eventually move the trailer, and a loose hitch can cause problems during transportation.
When it comes to the location for storage, you have two main options: indoor and outdoor storage.
Indoor storage is the ideal choice if you can afford it. A warehouse or a covered garage provides protection from the elements. Rain, snow, and extreme sunlight can all take a toll on your fuel tank trailer. Rainwater can cause rust to form on metal parts, and UV rays from the sun can damage the paint and the rubber components. If you're using indoor storage, make sure the area is well - ventilated. Storing a fuel tank trailer in a poorly ventilated space can lead to the buildup of fumes, which can be a fire hazard.
Outdoor storage is more common for many, but it requires extra precautions. If you're going to store the trailer outdoors, find a flat and dry area. Avoid low - lying areas that are prone to flooding. You can use a high - quality, breathable trailer cover to protect the exterior from the elements. However, just covering the trailer isn't enough. Place blocks under the frame to lift the wheels slightly off the ground. This helps to relieve pressure on the tires and prevents flat - spotting. Also, consider using tire covers to further protect the tires from UV damage.
Now, let's talk about maintenance during the storage period. Even when the trailer is not in use, it still needs some attention. Check on the trailer periodically, at least once a month. Look for any signs of damage that might have occurred due to weather or pests. If you notice any rust starting to form, use a rust remover and then apply a protective coating to prevent further rusting.
For the fuel system, if there's a small amount of fuel left in the tank, you can add a fuel stabilizer. This helps to prevent the fuel from breaking down and forming varnish or gum deposits, which can clog the fuel lines and injectors.


If your fuel tank trailer is equipped with a battery, remove it before storage. Batteries can self - discharge over time, and if left connected, they can damage the electrical system. Store the battery in a cool, dry place and charge it every few months to keep it in good condition.
Let's also touch on the importance of proper documentation. Keep a record of all the maintenance and inspections you do before and during storage. This documentation can be very useful when it's time to sell or transfer ownership of the trailer. It shows that you've taken good care of the trailer, which can increase its resale value.
Now, I'd like to mention some of the great fuel tank trailers we offer at our company. We have the 40 Cube Fuel Tank Trailer, which is perfect for transporting medium - sized amounts of fuel. It's built with high - quality materials and designed for maximum durability.
