| Description of the problem | Normal fill up of gas tank causes fuel to leak out of top of sending unit. The seam just below the electrical connection powering the units motor seems to be weakly and/or improperly joined, allowing raw gas to leak out and pool into a small compartment under the drivers side rear seat. When i purchased car used 14 months ago, i noticed extreme gas smell after 1st night in the garage. I immediatly took vehicle back to dealer where they replaced sending unit under 30 day warrenty. Now only 14months later after a normal fill up at a gas station and then driving home, i noticed a very strong gas smell as i entered the garage the next morning. I have found that i am not the only one with this issue. Online research lead me to information that gave me the details neccesary to locate and remove the access panel under the drivers side rear seat. After removing the top access panel under the seat i found (rough estimate) a measuring cup of gasoline that was pooled around the base of the sending unit. So much fuel had leaked that it had overflowed the pumps recess and had pooled into the surrounding (rubber/plastic) recess that seals the top of the sending unit from the outside. |
