Suppose your delivery trucks are all set for a busy shift. Or your tractors are gearing up for farm work. Suddenly, an unexpected issue hits, and it’s water causing trouble in the gas tank. It may seem minor, but it can complicate your plans and slow your business operations.
We must identify and promptly address the symptoms of water in the gas tank. The awareness of those tank particularly having water in fuel symptoms and their solutions is essential for a healthy engine and smooth vehicle performance. This blog will highlight those primary water in gas tank symptoms and their practical solutions.
How Does Water Get Into Your Gas Tank?
Water can sneak its way into your gas tank through various pathways, often unnoticed until it affects your vehicle’s performance. The most common causes include condensation from humid air, leaks or weak seals in the fuel system, and exposure to rain or flooding. Additionally, filling up at stations in high-humidity regions or leaving the gas cap off during wet weather increases the risk of contamination. Being aware of these factors can help you take preventive measures to protect your vehicle’s fuel system and engine from potential damage.
The three most common reasons for water mixing in gas tanks explained in detail:
1. Condensation
Water can enter a gas tank through condensation. Condensation happens when the temperature changes. The air inside the gas tank expands and contracts, creating moisture. Over time, this moisture can build up and eventually turn into water droplets.
2. Infiltration
Infiltration refers to the process by which water gradually seeps into a material or space. In the context of a gas tank, infiltration can occur when water penetrates the tank’s structure. Water can enter a gas tank through leaks and from contaminated fuel supplies via infiltration.
3. Faulty Gas Caps
Another way water can enter the gas tank is through a defective gas cap that does not seal properly. It can cause rainwater or other external water sources to seep into the tank.
Furthermore, weak seals in a fuel tank can also permit moisture to enter, especially in wet climates.
Common Symptoms of Water in Gas Tank
Detecting water in a gas tank can be tricky since symptoms are not always apparent. However, there are some signs to watch out for.
Are you scared there’s water in the fuel tank? Symptoms of water in gas tank may include:
1. Poor Engine Performance
Common symptoms of water in your gas tank include poor engine performance, rough idling, stalling, and difficulty starting. Water disrupts combustion, causing power loss and making the engine struggle.
Water in the fuel tank can lead to erratic vehicle performance and potential long-term engine damage. If you notice these symptoms, it’s important to address them to avoid further issues.
2. Engine Sputtering and Hesitation
If there’s water in your gas tank, your engine may sputter and hesitate during acceleration. Water contamination disrupts combustion, causing irregularities that make the engine struggle to maintain speed. This results in a jerky driving experience, especially when you try to accelerate.
3. Rough Idling on Injectors and Misfires
Most cars manufactured in the past two decades use fuel injectors instead of carburetors. These injectors spray the necessary fuel into the engine’s combustion chamber. When water mixes with the fuel in the gas tank, it disrupts the fuel’s density, which the injectors rely on to function properly. This imbalance puts stress on the injectors and can lead to engine stalling, as well as uneven firing of the engine cylinders, causing rough idling and misfires.
4. Causes Unexpected Engine Stalling
Initially, the engine may run fine, but over time, symptoms of water in your gas tank will appear. A significant amount of water in the fuel tank can cause unexpected engine stalling, leading to sudden stops while driving or idling.
5. Water In Gas Tank Produces Unusual Fuel Smell
If you notice an odd smell coming from the fuel, it could indicate that there’s water in it. Water can alter the typical gasoline smell, creating a strange and unpleasant odor. This unusual smell is a strong sign that water might have entered the fuel system, so it’s important to check it out to prevent further issues with your vehicle’s performance.
6. Decrease in Fuel Efficiency
Water in your gas tank can reduce fuel efficiency. Since water is heavier than gas and doesn’t combust, it disrupts the engine’s fuel use, leading to increased consumption. Consequently, you may find yourself visiting gas stations more often, even under normal driving conditions.
Signs of Water in Your Gas Tank and How It Affects Your Vehicle
Water in gas tanks can seriously damage vehicles because it’s chemically different from gasoline and diesel. Preventing water from getting into the fuel by early locating the problem of having water in gas tank symptoms is essential to avoid issues with your vehicle, such as;
1. Water In Gas Tank Shows Corrosion and Rust in The Fuel System
Water in the fuel tank starts a corrosive process that can cause rust and corrosion. This leads to big deposits of debris in fuel lines and spark plugs, often exacerbated by the presence of ethanol. The inside of the gas tank is especially vulnerable, and over time, the corrosion can spread to other important parts of the fuel system. Corroded parts weaken the structure and might cause fuel tank leaks and other problems.
2. the Engine Becomes Less Efficient Causing Fuel System Failure
Water in the fuel system creates a poor blend, causing the engine to operate inefficiently. This results in lower mileage, requiring more frequent refueling and increased costs for running your vehicle.
DIY Diagnostic Tests for Detecting Water in the Fuel Tank
Wondering what to do if you get water in your gas tank? Don’t panic, let’s understand the two tried-and-true DIY diagnostic tests for detecting water in fuel:
1. Visual Inspection Tips
To check for water in the gas tank, drain a few ounces into a clear glass container. Let it sit for 30 minutes to allow separation. Water, being heavier than gasoline, will settle at the bottom, forming a clear layer. Inspect for signs of water contamination by looking for a gelatinous layer beneath the gasoline.
2. Using Water Detection Additives
A reliable way to check for water in your gas tank is to use water-detecting additives. Apply a small amount on a dipstick or wooden stick, insert it into the tank, and look for signs of water. If there’s water at the bottom of the tank, the paste will change color.
” While professional diagnostics are ideal for precise evaluation, simple DIY methods exist to identify potential water contamination. If you suspect water has contaminated your fuel supply, there are two ways to check for the presence of water. If either method results in a positive test for water in the fuel, your best action is to drain the fuel tank completely and refill it with fresh fuel.
