How do you know if there’s water in your gas tank?
Water contamination doesn’t always announce itself, but a few symptoms tend to show up first:
- Hard starting. The engine cranks longer than usual, or it takes several tries before it fires up.
- Rough, unstable running. The bike or car runs unevenly, hesitates when you open the throttle, or surges and jerks instead of accelerating smoothly.
Common signs of water in your gas tank
Here are the symptoms to watch for in more detail:
- Difficulty starting. This is especially noticeable after the vehicle has been sitting unused for a while.
- Unstable operation. Water in the fuel disrupts combustion, so the engine may stumble, jerk, or fail to pick up speed when you accelerate.
- Strange noises from the engine. Unfamiliar knocking or sputtering can be a sign that water has made its way into the fuel.
- Weak performance. The engine feels sluggish and never quite reaches its full power.
What causes water to get into the gas tank
A few different things can let water into your fuel:
- Fuel system faults. A worn or imperfect fuel system can allow water to seep in over time.
- Condensation inside the tank. Air trapped in the tank can condense into moisture and mix with the fuel, especially with temperature swings.
- Poor storage. Storing fuel in a humid environment, or leaving the tank exposed to the elements, makes contamination far more likely.
How to fix water in a gas tank
Once you suspect water in the tank, here’s how to deal with it:
- Inspect the fuel system and repair any faults. Check the components tied to the fuel system and fix anything that could be letting water in.
- Drain the old fuel and refill with fresh gas. Empty the tank completely so no water-contaminated fuel is left behind, then fill it with clean fuel.
- Check the tank and seal out moisture. Examine the tank and its fittings to make sure no water vapor can get back into the system.
How to prevent water in your gas tank
A little prevention goes a long way:
- Store fuel somewhere cool and dry. Keep it away from high humidity and out of direct sunlight.
- Check your fuel system regularly. Make sure everything is working properly so water doesn’t have an easy way in.
- Park under cover. When you leave the vehicle, choose a spot with a roof or some protection so the tank isn’t sitting out in the rain.
When to call in a professional
If you think the contamination is serious, take the vehicle to a trusted repair shop and have it checked properly. An experienced technician can clear the problem quickly and make sure nothing else was damaged in the process.
Water in the gas tank is manageable once you know what to look for. Keep an eye on the warning signs, follow the prevention tips above, and your engine will stay reliable for the long haul.
