Tank Filler Pipe And Cap Problems of Chevrolet Uplander

A short time after filling my gasoline tank I began to detect the strong odor of gasoline fumes. I thought I had overfilled the tank so I ran out some gas for a few miles, but the odor of raw gasoline would not go away. I looked under the vehicle to see if there was any gasoline leaking and saw what appeared to be gasoline running down the drivers side of the gasoline tank. I could not detect the source of the leak so I took my vehicle to a local automotive repair shop. The mechanic removed the gasoline tank and discovered that the source of the leak was a crack in the plastic gasoline return line going into the internal tank module. This leak created a very hazardous situation that could have resulted in a serious fire if the raw gasoline had come into contact with the hot exhaust tail pipe or catalytic converter. The mechanic told me that this is not the first time he had repaired this type of leak. There was no physical damage that he saw that could have caused the plastic return line to leak. I feel that this is a serious flaw in design or material and should be brought to the attention of other owners of a Chevrolet Uplander Mini van.

A short time after fuleing my gasoline tank I detected a gas odor. The odor did not go away, but got worse. I checked under my vehicle to see if there was any gasoline leaking and saw raw gasoline leaking down the side of the gas tank on the driver side. I could not determine the scource of the leak so I took my vehicle to a local repair service. The mechanic determined that the leak was coming from a plastic fuel line attacjed to the internalo fuel tank module. There was a crack in the plastic fuel line and gas would spray from this crack onto the top of the gas tank, eventually running down the side of the tank creating a very hazardous situation. I feel that fuel could have sprayed to the other side of the tank (exhaust pipe side) and could have caused a serious fire.

The problem is with the gas tank filler neck, the flap at the neck is missing and may have fallen in the gas tank. Uplander van has 7,800 miles on vehicle. I will report this to the dealer casa chev.
