Four problems related to tank assembly have been reported for the 2003 Mercedes Benz E320. The most recently reported issues are listed below.
My wife was driving home from work when she smelled a noxious gasoline odor. Took car for repairs on Aug 23, 2013. Had to replace the auxiliary (sending) pump and the cable harness attached to the fuel tank. Mercedes has had numerous issues with the fuel tank and pump but they refuse to do a recall and fix the problem. This repair cost $664. 18 to fix items that are inherently defective in the mercedes vehicles.
After filling the gas tank there was a strong smell of gasoline and leaking fuel near the drivers side rear tire. Upon calling a mechanic they said to look under the seat for leaking fuel. The fuel sending unit was definitively leaking.
Sending unit leaks gasoline into the cabin of the vehicle letting in intense fuel vapors as well as actual liquid fuel into the cabin. Furthermore the faulty sending unit causes a fuel leak from the gas tank to the exterior of the vehicle leaving puddles outside of the car while parked and continuing to leak while driving. Both of these pose an extreme danger of fire hazard, as well as a health risk from constantly inhaling gasoline fumes.
The gasoline tank on my 2003 e 320 mercedes had a leak on the top portion of the tank. This allowed fumes to leak into my garage and would have presented a huge fire risk had I not discovered the problem and been involved in a rear end collision. A gas tank should not fail under normal wear and tear.
