So when i first owned it I was able to pump gas and leave it there. Now I can only pump a gallon then wait 2 seconds and repeat other wise it would spill out. I made an appointment the dealer. We went to the closest chevron and it pumped fine, he even let me try.
He explained the rubber stopper on the pump needs to be all the way in to be held. Well all my gas stations in my area(SF) have these steal type stoppers that won't keep the pump in past a gallon.
I think my car has a problem cause it should pump gas like all other benz in S.F. What might be my problem and should it be covered under the "extended fuel leak issue" ?
Have a 05 c55, 07e550 and 06 ml350 with no issues with fueling with the same pumps.
First picture, that steal part was a rubber part when we went to chevron by Autobahn motors Dealer. But everywhere I live its steal.

I'm not 100% sure. But I was having this exact problem. The conclusion I came to way there there was TOO good of a seal at the nozzle therefore is was preventing air from escaping the tank, so gasoline and oxygen would fight for the space..

I've had the issue a few times. I fill up on the slowest click. Insert the nozzle barely to allow any pressure to vent for a few seconds before inserting all the way...lol

Same. Tho sometimes that doesn't even do it.

I got an appointment next week with dealer again. I've tried on the slowest click and venting. When i first had the car, no problem pumping. I feel something is worn or something. Please Anyone else that had this problem fixed? I would like to go dealer with and idea whats going on and if its covered under the extended warranty.

it could be your charcoal canister causing this issue. it may be saturated with fuel. one way to check is to remove the vent line from the canister and then attempt to refuel.

This sounds a lot like what happened to my Tacoma truck. The problem was that there was debris partially blocking the filler tube "screen" at the fuel tank. To examine and retrieve the debris, I had to disconnect the fill hose right at the tank and look down inside with a mirror and flashlight. I found a piece of plastic sitting on the screen. Tell the dealer to check this area when they look at it.

That was my problem. If OP does a search, OP will find my threat/response with pics on the canister. It was an easy fix. I bought the part used from Shardul and it took me less then 45 minutes to install. You have to remove rear passanger wheel and the wheel well protectors.
