The car has fuel (gasoline) vapors inside and outside of the car. The fuel sending unit or the fuel pump in the saddle gas tank under the back seats leaks gasoline and the smell makes me sick. I am afraid the car will explode if the vapor is present at the combustible ratio of gasoline to air.

The fuel pump and/or gasket is leaking gasoline into the area under the back seat on the drivers side. The first time we noticed the problem was on nov 1, 2012, but it has happened several times since then. We can no longer fill the tank to the full position without fuel leaking. We have replaced the fuel gasket, but it has since leaked again. This is a great safety concern to me, and it should be corrected by mercedes benz at no cost to me.

I brought my 2005 mercedes e320 [purchased oct. 2014] in for an oil change jan. 30, 2014. I mentioned to the service person a noise [like something broke] I heard while out of town visiting. He changed my oil and also found/replace a broken rear suspension spring. This occurred within 3 months of purchase. Repair cost: $551.17. My second incident occured feb. 19th. I noticed a puddle of fluid underneath the vehicle [not sure what kind of fluid] and immediately brought the car back to the dealer for service. I was told the transmission servo solenoid seals required replacing. Repair cost: $157.84. The third incident was reported apr. 21, 2014. I noted an increasingly bad odor inside the car since the first day of purchase, but wasn't sure exactly what it was as I was still trying to identify it. I finally realized it was gas I was smelling [intermittantly] inside the vehicle for the last six months. It turned out to be leaking fuel from the left fuel pump seal (lfps) underneath the rear seat. Repair cost: $161.31. The fuel odor got worse after the replacing the lfps. Most noticeably after filling the car with gas. I've also identified gasoline leaking from the drivers' side rear quarter that puddled by the tire. My feeling at this time, repairs may be onging for my e320, that I really like.

We start notice gas fumes smell when we filled our mercedes-benz up with gas & as we drove our vehicle the gas smell would stop, approximately 30 miles plus. As the months went on the incident would get worst at each fill-up. Sometime around february the check engine light came on so we took the vehicle to repair shop & they found gas leakage around the fuel pump under the back seat. As of today the issue is still going on with the gas smell.

When the fuel tank is filled 100% there is a very strong fuel odor, which can be smelled in the outdoors but is extremely strong when parked in the attached garage. This odor is so strong that it enters the house, and we have to leave the garage door wide open for fear of a spark causing a fire. If one looks under the car there is no dripping. The odor does not go away until the fuel tank is no longer completely full. The fuel leak stops after we are down a couple gallons from completely full fuel tank. I have pulled the back seat and seen that the there is gasoline pooling around the fuel pump (fuel delivery module). I am concerned that a rear end collision would cause the leaking fuel to combust.

The car has a strong gasoline smell both in the passenger compartment as well as outside the car after filling the gas tank. This smell persists for several days, until the tank gets to below 3/4 full, at which time the fuel smell goes away. The strong fuel smell returns when the tank is again refilled to full capacity. The seals around the fuel pump and sending unit at the top of the tank were replaced twice with factory mercedes-benz parts by a qualified mechanic, and this has not stopped the problem. There appears to be a leak in the gas tank or other fuel system component. The mechanic inspected the fuel sending unit and did not see any fuel leaks at that point, leaving me to suspect a leaking gas tank.

I've had the smell of fuel in my e320 base model for about 2-3 months now. I didn't pay it much attention until now (3/31/2012) when I did a little research for myself and found a leak from the fuel pump to fuel line housing. I did not take pictures but the hose line connection to the pump was cracked and upon taking hose off pump housing, the housing connection snapped completely off. In the process of trying to find another fuel pump now because vehicle is disable.
