How to Keep Gas Tank from Rusting after Cleaning? Easy Guide in 2023

Gas tanks are currently becoming more contaminated and corroded. As a result, there is now a greater demand for various polishing and rust-prevention solutions. This post is absolutely for you if the idea of having rust in your gas tank disturbs you.

Several long-term consequences can result from corrosion in gas tanks. Heat and humid conditions can cause corrosion. In the warmer months, the heat causes the tank to create water, which may then lead to the gas tank rusting. The water left behind after cleaning the tank is undoubtedly another source of water in the tank.

Being careful is possible. Rust always manages to make its way to your gas tank, despite your best efforts to prevent it from happening. Moreover, it causes issues including filter clogging, impairing release sensing, diminishing fuel lubrication, and ultimately causing equipment failure.

Don’t worry, though, if you have already read this far. No matter how often you clean your gas tank, we’ll give you some advice on how to prevent rusting in this article. So let’s go right to the point.

How to Keep Gas Tank from Rusting after Cleaning?


How to Keep Gas Tank from Rusting after CleaningWe’ve listed eight actions you may do to prevent your gas tank from rusting easily below.

1. It’s a good idea to store fuel in a double-skinned tank.

The dual skin of a tank offers twice the defense against climatic changes and impact damage. It serves as a safety net to prevent leaks and detects them. A double skin ensures that the gasoline tank is enclosed within a vacuum to prevent corrosion because there is no prospect of moisture or air getting in.

2. Paint the tanks with a coat.

A corrosion-resistant finish, such as Hammerite Direct to Rust Metal Paint, can protect the tank for a lot longer by repelling water and preventing rust from building up beneath it.

3. Install an additional containment system.

Legally, any spills that might come from tank penetration must be contained and prevented via a concrete or brick bund (secondary containment). In order for the outer bund to be able to safely hold water if there is a leak, the tank is overfilled, or water develops in the tank, it must be able to retain 110 percent of its contents.

4. Install a bung and a valve.

The drawback of an outside bund is that it is exposed to the elements and is likely to accumulate rainwater. Over time, this accumulation might build up and allow oil to leak by breaching the wall of the bund.

It is essential to adopt forceful measures, such as employing a valve, to collect rainwater from exposed bunds. This needs to be kept shut at all times, however it can be opened to drain any clean water.

Dewatering the tank at the outlet pipes, maybe with the use of a bung, is another method of preventing leaks. This will reveal any liquid oil-water interactions. To let water out while maintaining oil in the tank, it should be positioned 14 inches from the bottom. Every six months, tanks need to be dewatered to avoid corrosion brought on by water buildup.

5. Review the fuel

Early detection of contamination is necessary to allow for the identification, diagnosis, and correction of any problems. It is advised that you carry it out every six months so that you can take preventative action rather than reacting.

Fuel that has already been contaminated has a higher chance of doing so again as its stability declines. You’ll be able to respond quickly if pollutants occur by routinely checking and evaluating the condition of your fuel.

During a fuel analysis, viscosity, density, microbiological contamination, water, FAME, and sulfur concentration are all assessed. The inside compartments of your gear or equipment may suffer serious problems from contamination, being irreparably destroyed or, even worse, ceasing to function.

6. Fuel polishing

Analyses will be used to gauge how polluted the gasoline is. If the quality of the fuel hasn’t significantly declined, polishing can be done. This labor-intensive process involves removing contaminated fuel twice to get rid of water, sediment, and microbial contamination.

Depolymerization, which removes particles and polishes the gasoline to like-new condition, happens after filtration.

The approach can be less effective if the polished fuel is retained in the same tank because gasoline polishing just recovers the fuel itself. As a result of the tank’s exposure to contaminated fuel, microbial growth developed on its inside, recontaminating the previously polished fuel and returning you to square one.

In light of this, the usage of other services may be required, especially for firms that completely rely on backup power, and fuel polishing alone may not be adequate.

7. Cleaning the tank

Fuel must be drained from the tank before it can be cleaned and disinfected during tank cleaning. Industrial vacuums are typically used to remove microbial growth, sludge, and heavy silt build-up that accumulate at the tank’s bottom, walls, and struts.

The contaminated gasoline may then be cleaned and refilled into the clean tank, or if it has gone too far, it can be disposed of.

8. Keep your gasoline tanks full.

Keeping fuel tanks full reduces air space, which results in reduced humidity and condensation, particularly during the hot months.
