Hi guys
i need help please! The problem is when i fill up tank the pump nozle is kicking back after 2-3 litres going in tank.. This is getting on my nervs and i want to fix it by myself.. I've searched in internet and some says its some kinda gas vent filter near gas tank but i cannot find some pictures with it.. Then i read something about charocal canister whats underneath rear bumper but its f@@kin expensive...
somebody had same issues? Any advise would be helpfull

Does it happen at all stations/ pumps ?
The reason might be a build up of pressure in the tank, so when you fill-up, the nozzle detects the pressure / fumes and stops pumping, thinking the tank is filled to the top. The problem likely will be in the vapor venting system, maybe an issue with the canister, lines, or the purge valve..

Also, are you the type that tries to squeeze in the last few drops of fuel by pumping after the first nozzle shutoff? Over time that can completely fill the carbon canister with gasoline.

This just happened to me.it always happens at this one mobil gas station.

You have to push it really hard to get maybe 5 seconds of fuel before it cuts off again.

This used to happen to me when i first got my C63 but now that i think about it, it went away on its own. Curious what it may be

Where is this filter located? Can it be drained or does it have to be replaced?

I'm assuming it's next to the fuel tank on the filler (passenger) side. If it's totally flooded I'd think replacement is in order, otherwise it'll eventually dry itself out.

If it only happens at one station it may be that the flow rate at that pump is set too high. If it is set too high the vent system cannot handle the flow and the pressure will back up the fuel coming in and shut the pump off at the nozzle. Try to hold the lever at half flow and see if it works. Your system may also be partially saturated with gas and causing the fuel vapors to back up. Never try to get the last drop into the tank. Once the nozzle kicks out do not try to force more fuel into the tank by clicking the lever. If the pump is working properly and your venting system is in good shape your tank will be as full as it is designed to be.

I'll try again as I only got 3 gallons of gas before I gave up.it would not flow fuel for more than 3 seconds and a time and I just left

Even if it works holding the lever below full flow it will be aggravating and I know I would not be happy and not likely to return. If you have other options it might be best to stick with them. If the station is convenient or you like it I would check inside to see if you can find out why that pump is set like that. Maybe you can find someone with a clue and get it adjusted or report it and see if it gets adjusted. The pumps are mechanical and can go out of wack from time to time and the staff may not be aware of it. It drives me crazy when it happens, which is not often fortunately, because I stick to one Shell station locally that is well run.

I stick to this one station because I watch my cylinders in mode 6 data for miss fires and this one station literally has the best gas I have ever tested.

i did it when i bought car.. i needed to drive home 2000 kilometers and didnt wanted to stop many times for filling up so i tried to squeeze in as much as possible.. also i shaked car littlebit so air can come out completely and i can squeeze more fuel.. didnt know that can cause problems

Same problem no solution yet.

Sorry for not responding to this thread long time ago. So my problem was solved by replacing Charcoal canister. It's under rear bumper right side. Need to remove wheel and wheel arch liner. First I removed canister let the pipes laying there freely and went to gas station to check if that's the problem. Sure it was. So only option was to change it. It can't be opened to change charcoals. By blowing with mouth it felt normal but there was some resistance. So mistake what I did was filling up gas till the nozzle kicks back 3-5x times couple of times filling her up. That's soaked up charcoal canister and clogged up.

Yep, that's it. I did it to my Chevy truck and boat owners in the marina I work at do it all time time. Once it clicks off the first time, do not try to top it off.
