The fuel tank holds the gasoline your engine needs to produce the power that moves your car, van, SYV, or pickup. That fuel is delivered to the engine via a fuel pump that typically sits inside the fuel tank. The fuel is sent to fuel injectors located in the engine cylinders. The gas mixes with air inside the combustion chamber, feeding optimized engine performance.

Fuel tanks are typically made of metal or a plastic high-density polyethylene (HDPE). Metal tanks are either steel or aluminum, and effectively limit emissions. Plastic tanks can be formed into various shapes, allowing them to be placed in ways that improve safety and conserve space. Fuel tank sizes range, with SUVs typically equipped with much larger tanks than those found in compact cars.

How to Spot a Failing Fuel Tank

Even top-quality fuel tanks can eventually go bad. Components in plastic fuel tanks are integrated into the tank's mold and can't be replaced when they do. Metal fuel tanks may rust and cause flakes to befoul your fuel. Signs of failure include:

Fuel leaks

The odor of gasoline in the air

The "Check Engine" dash light comes on
