How do I check my fuel system after a flood?
How do I know if there's water in my gas tank or fuel system? My neighborhood got hit pretty hard by a recent hurricane. Luckily, our building is okay and we didn't have any issues with our home. Our car, though, is a different story—the garage where we park was completely flooded. I know I need to check my fuel system for water to get a sense of how bad the damage is, but I've never had to do this before and I'm not sure where to start.
- Check the waterline. This is the best way to confirm how deep the car was submerged. If the water reached the bottom of the doors, odds are that you’re fine; just let the undercarriage of the car dry out before starting it. A waterline at the top of the wheel rim is a bigger concern, as some electronics were probably submerged. And if it appears the hood was underwater, there is a very good chance that water got into your engine—meaning you might be looking at a heavy amount of damage.
- Check for signs of water entry. If the air filter and intake are wet, it’s highly likely that water got into your engine elsewhere, too.
- Remove as much water as possible. If you find any water, drain the tank and lines and change the fuel filter.
