Do These 4 Things If You Have Water in Your Fuel Tank


Water in your fuel tank is a serious issue requiring immediate attention. Water can cause severe damage to your engine, reduce fuel efficiency and performance, and lead to costly fuel tank repairs if left untreated. If you suspect or confirm that your fuel tank has water, there are four things you should do immediately.

Drain the Fuel Tank

The first step in addressing water in your fuel tank is to drain the tank completely. This involves removing any remaining fuel and water mixture from the tank, either by siphoning or using a fuel pump. It’s important to do this soonest to prevent water from causing further damage to your engine.

Before you begin, ensure the fuel tank is empty, and no fuel is left in the lines or filter. You may need to disconnect the fuel pump or filter to drain the tank completely. Once you’ve emptied the tank, dispose of the fuel and water mixture appropriately.

Clean the Fuel System

After draining the fuel tank, you must clean the entire fuel system to remove any remaining water or debris. This includes the fuel lines, fuel pump, fuel filter, and fuel injectors. Water can cause corrosion and rust, which lead to blockages and damage to these components.

You can use a fuel system cleaner or have a professional mechanic clean the fuel system. A fuel system cleaner will help remove any remaining water and debris, improving fuel efficiency and performance. Choose a cleaner that is compatible with your vehicle’s make and model.

Refill with Fresh Fuel

Once you’ve drained and cleaned the fuel system, you must refill the tank with fresh, clean fuel. This will dilute any remaining water and prevent corrosion and rust from forming in the fuel system. It’s crucial to use high-quality fuel to prevent further fuel system contamination.

When refilling the tank, fill it to avoid any air pockets that can cause fuel pump damage. Additionally, it’s important to avoid overfilling the tank, as this can cause fuel to spill and create a fire hazard.

Prevent Future Contamination

One way to prevent contamination is to purchase fuel from a reputable fuel station. Avoid purchasing fuel from low-priced stations, as this can indicate the fuel is of poor quality.

Another way to prevent water contamination is to inspect your fuel system for leaks regularly. A leaking fuel line or fuel tank can allow water to enter the fuel system, causing damage to your engine. If you notice any leaks, get the fuel tank repaired immediately to prevent further damage.

In addition to these precautions, you can add a fuel additive to your fuel tank. Fuel additives help remove water or debris in the fuel system, improving fuel efficiency and performance. Be sure to choose an additive compatible with your vehicle’s make and model.
