Cleaning Rust Out Of A Generator Gas Tank

Rust is always a bad thing. It is the result of a chemical reaction between oxygen and metal (usually the iron in your car’s steel parts), and it jeopardizes the integrity of your equipment. Rust, if left unchecked, has the potential to destroy it.

How To Clean Rust Out Of A Generator Gas Tank?

Rust is especially vulnerable in your gas tank, including on the inside, where it can spread without your knowledge. However, rust in the gas tank endangers not only the tank but also the overall health of the generator.

Following are the steps for repairing a gas tank to get rust out of it:

1. First And Foremost, Safety!

When working with fuel systems, keep in mind that gas is highly flammable and can be hazardous. Before you begin cleaning your gas tank, consider the following safety precautions:

To help prevent an accident, keep your work area clean and organized. If you’re working inside, make sure your workspace is well ventilated open any doors or windows, and use a fan if necessary.

Keep a fire extinguisher nearby. Make certain that there are no sources of flame or spark in the area.

Put on your mask. Wearing a face mask can help reduce the number of fuel fumes inhaled.

2. Empty The Tank

Make sure the tank is completely empty of fuel before removing it. This is not only a safety precaution, but it also relieves some of the strain, making the entire process easier.

A drain cock on some gas tanks allows the fuel to be drained neatly. If not, drain the fuel by disconnecting a gas line or siphoning it.

3. Take Out The Tank

This can be simple or complex depending on the type of engine. Remove the gas tank with care, but leave all valves and caps in place.

This will greatly simplify the re-installation process later on. Once it’s out, thoroughly inspects the tank for sediment, rust, and any holes. Before proceeding, repair any holes.

4. Clean The Tank

Make use of a good parts cleaner. Shake or swirl the product to distribute it evenly across the entire inside surface of the tank.

Keep in mind that the majority of the buildup will be on the bottom, so concentrate your efforts there. Depending on the amount of buildup, it may take several soaking sessions to completely clean the bottom.

5. Decontaminate The Fuel System

To ensure that all of your tank-cleaning efforts are not in vain, run a detergent-based fuel additive through your fuel system.

6. Change The Fuel Filter

This appears to be common sense, but it is frequently overlooked. If you’re going to the trouble of cleaning your tank and lines, you should also replace the fuel filter. A clogged filter restricts flow throughout your entire fuel system, causing your fuel pump to work harder and wear out faster.

7. Return It To Its Proper Place

When replacing the tank after cleaning it, make certain that all valves, caps, and hoses are securely fastened. If there is even a minor gas leak, there is a risk of environmental damage or a fire.

How Can We Avoid Corrosion In Gas Generator?

Cleaning your gas generator properly ensures that no dust, grime, or other harmful materials enter your engine and cause damage. Maintenance also prevents fuel lines from clogging and keeps your fuel pump running at peak performance for a longer period of time.

Because of the nature of the products stored, some corrosion is unavoidable; however, there are several techniques and materials that can be used to prevent it. Most importantly, a proactive rather than a reactive approach must be used to maintain fuel quality and avoid downtime in operations.

Fuel Should Be Stored In A Tank With Two Skins

A tank with two skins provides twice the protection against temperature fluctuations and impact damage. It detects leaks and acts as a safety net to prevent leaks. A double skin keeps the fuel tank contained within a vacuum, preventing corrosion by preventing moisture and air from entering.

Tanks Should Be Coated With Paint

Using a corrosion-resistant finish will keep the tank protected for much longer by repelling water and preventing rust from forming beneath.

Examination Of The Fuel

Contamination must be detected early on in order to source, diagnose, and repair any problems that arise. As a result, every six months is recommended in order to take a proactive rather than a reactive approach.

Once the fuel has been contaminated, it is more likely to become contaminated again as its stability declines. Checking and testing the condition of your fuel on a regular basis to monitor any recurrences of contaminants will allow you to act quickly.

Cleaning Of The Tank

Tank cleaning necessitates draining the fuel from the tank so that it can be cleaned and disinfected. Industrial vacuums are typically used to remove microbial growth, sludge, and heavy sediment build-up from the tank’s bottom, walls, and struts.

Related Questions

What is the best way to clean a generator gas tank that has been sitting for a long time?

You want to get as much as possible out of it. Slosh some liquid around in the tank to try to get additional loose particles from the surfaces, which you may subsequently remove. Next, look for trash or deposits in the existing fuel filter. Reinstall it if it appears to be in good condition.

What is the best way to get the rust off a gas tank?

Filling (or nearly filling) the tank with vinegar and baking soda is the safest way of chemical rust removal. Allow the mixture to settle until it bubbles, and the rust particles begin to change color. Then give it a good rinse to make sure it’s entirely empty.


The lifetime of any equipment can be easily lessened if it starts to rust and it would be even worse if it happens to your gas generator. The ultimate solution to avoid rust is to maintain your gas tank regularly.
