Checking the fuel system (Chevrolet Tahoe 1)

1. The fuel system is best checked with the vehicle raised with a hoist or on stands to provide access to the components from the bottom and to make the work as easy as possible. The main fuel tank is mounted in the rear left side of the vehicle.

2. If you smell gasoline while driving or after parking your car in the sun, the fuel system needs immediate and thorough inspection.

3. Unscrew the fuel filler cap and check it for signs of corrosion and damage to the gasket. Replace the cap if necessary.

4. Check the condition of the tank and filler pipe while under the car. Pay special attention to the connection of the filler pipe to the tank. Punctures, cracks and mechanical damage are not allowed.

5. Carefully inspect all rubber hoses and tubes coming from the tank. Check the reliability of the connections, the presence of signs of wear, pinching and other damage on the hoses. Especially carefully inspect the condition of the ventilation tubes and tank hoses, which often wrap around the neck and get pinched or clogged. Monitor the condition of the hoses along their entire length, to the front of the car. Replace damaged sections of the pipelines.

6. If after checking you still smell gasoline, check the gasoline vapor recovery system (see below).
