Best Repair Shop in Lowell for Fixing Your Subaru’s Rusted Fuel Tank

by Mechanics Direct October 10, 2024

Have you noticed fuel smells in your Subaru, or was there any sign of rusting recently in the undercarriage? If yes, then it might just be time to take your fuel tank for a much closer look. Corrosion in a fuel tank is not just a surface problem; it can actually affect the performance of your vehicle to the extent of leaving you stranded. Let’s get more information on the causes of fuel tank rust and how to deal with this problem in Subarus.

Why Does a Subaru’s Fuel Tank Rust?

• Moisture and Condensation: If you often drive with a small quantity of fuel in the tank, the empty space will lead to condensation of moisture. This moisture gathers at the base of the tank, and because of this rusting occurs more frequently especially if you are in areas with high humidity.
• Age of the Vehicle: Needless to say, older models of Subaru automobiles have a higher probability of developing rust because their metallic body has been exposed to environmental factors and there would have been wear on the protective layers. These coatings often deteriorate with time and as a result, the metal is not protected as required.
• Contaminated Fuel: Any fuel that has water content or some other kind of contamination will increase the rate at which rust forms on the interior of the tank. Bad quality fuel brings in water that settles and causes rusting of the tank.
• Environmental Factors: Rust is more likely to occur if a car is parked in a humid environment, a place that experiences frequent rainfall, or a country that has snowy winters. Salt used on the roads during winter is very abrasive and can cause early rusting on the outer part of the fuel tank.

How to Treat a Rusted Subaru Fuel Tank

You should not hesitate if you see signs of a rusted fuel tank including fuel smell, leakage, or poor engine performance. Rust can affect the fuel system and can also be a safety hazard. Here’s how professionals handle the problem effectively:

• Assess the Damage: The first thing to do is to check the level of rust on the fuel tank and whether it can be painted. The outer rusting may be washed off but if the corrosion has gone deep and affected the integrity of the tank, replacement will be required.
• Drain and Remove the Tank: Since rust particles can easily find their way into the fuel system, the tank is emptied of all the remaining fuel. The tank is then taken out of the car to enhance the effectiveness of the cleaning process.
• Clean the Tank: The rust is removed using certain tools and methods that are aimed at cleaning the tank. Chemical rust removers dissolve rust and make debris to come off easily for easier cleaning. After cleaning the tank, it is then washed and dried so as not to encourage further rusting on the tank.
• Apply a Protective Coating: After the tank has been de-rusted it is then coated to seal the metal and stop any further rusting. This step is very important if one wants to get an extended life for the fuel tank.

When Replacement Is Necessary

Sometimes, the rust may spread to areas that cannot be cleaned or repaired easily. In the event that the fuel tank has some large holes or structural compromise, replacement is the best and most advisable course of action. This may look expensive but it helps ensure your Subaru is both safe and running efficiently.
