FIX Gas Leaking When Filled Up of W212 E350 (Part One) 修理油箱漏油 (第一部分）

If you think my work is worth it www.paypal.com/donate?hosted_...
Welcome to leighsr.com to discuss.
Whatever W210, W211, W212, there are tons of complaints that issue occurred online. I also encountered the same problem, the gas (Petrol) smell when filled up the E-class gas tank, especially in the garage. That is the fuel leaking. Rather than arguing with the dealer, it's better to spend a few hours and a few money to fix it by ourselves, especially with an expired warranty.
The parts I ordered:
Fuel Tank Seal Ring 211471017964 ebay.us/PWoLQg
Fuel Pump O-Ring Lower amzn.to/3owOso5
The tools I used:
DeWalt Impact Driver Socket Adapter amzn.to/2MSUcY3
DEWALT 20V MAX XR Impact Driver, Brushless, 3-Speed, 1/4-Inch, Tool Only (DCF887B) amzn.to/2Jj5lTJ
Husky tool chest amzn.to/315Ua7p
Wera amzn.to/3hnqN6q
Kobalt 5-piece Pliers Set amzn.to/2NiOw9Y
我在网上看到，很多W210、W211、W212的车主都遇到过这种问题，我也没躲过去：加满油后，闻到汽油的味，在车库里尤其明显，那是汽油泄露了。车过保了，与其去4S点纠缠，不如自己花点时间，花点小钱把问题解决了。

Watching Senior Leigh is so therapeutic, that I watch him work even when I don't need to repair my Mercedes-Benz!

[@norrisspencer7600]

I have watched a lot of how to videos to fix things on my vehicles. This is by far, the BEST, how to video I have EVER seen. Thank you very much for this.

[@williamlegall2988]

When I drop in on a Senior Leigh video, I instantly feel great. I forget everything negative in life, and all is perfection. Thank you Senior Leigh!!!

[@tonychavez2083]

Great video, no lame music, no overdone commentary, just clear cut process. I swapped my whole pump out since it had 230K miles on original pump. Thanks for posting.

[@Mirarty]

Very common issue on mercedes gasoline cars. Relatively easy and cheap fix. Some people use epoxy to fix that plastic part, some people replace whole pump. Make sure you gas tank has minimum gas inside and have open garage door and good airflow otherwise you will have headache. Nice video as always, thank you for sharing!

[@wk5020]

Thank you Senior Leigh.

[@akidim13]

Gonna do this to my GLK350 , thank you so much , easy peasy

[@michaelliu1162]

就喜欢看李哥修车，舒服😌。

[@edwinhandybuddy1038]

奔驰是很好的车，但总是在一些小部件上出问题。您拍的所有视频我都看了，受益匪浅，谢谢。

[@LeighSr]

是啊，这个漏油的问题延续几代E-class了。谢谢您的关注🙏

[@1068andy]

Thank you for the good quality video and the helpful information

[@stevey4131]

Welcome back! Long time no see!

Also, this is a matter of the high temperatures in California and etc. As my W211 is in California as well. Consider how hot the interior gets in the California Sun. With my 212 (2014 E350 W4M) in Toronto I think this is less of an issue.

[@hamzayagan]

Great video as usual

[@AlvinShen]

Had an issue with my W211 E350 Fuel Tank. Ended up being covered under the recall.

[@bigboycars]

Great Job!

Hi Senior Leigh. This posting was terrific. Incredibly professional and detailed. I used it to swap my exact same parts on the C300W 2011. Question though - what is the correct torque wrench value for the steel ring on the C300W?

[@LeighSr]

Thank you and the nuts on steel ring is 5Nm for all of models at 7:17

[@drewmuhammad40]

What size nut are you using to take the black cover off? And do those bolts come out easy

[@yahircruz282]

Great vid :D

[@petersun5788]

老李终于更新了，换之前没有检查塑料盖子好坏吗？

[@LeighSr]

拆下盖子清洗的时候，已经发现有裂痕了，但苦于没有配件，只好先装回去了。下集完美解决😂

[@michaelg4334]

Would this issue cause a check engine light to turn on

[@Airdrifting]

I have a similar problem with my 2014 W212 E350, but I was told by a Mercedes mechanic that there is a gas filter under one side and gas pump under the other, how come there is no filter or pump under the cap you removed?

[@Diamondblend]

so it wasnt the pump? just the rings?

[@live5624]

油箱通風有問題嗎？檢查看看喔！

[@eddielam9750]

李sir你好、我的車子是2012 Mercedes Benz C 350 M276 engine , 我車子上星期二突然打不著engine 而當按keyless button時、我聽到有二下engine kick kick聲、我連續試了四次最後打 得著engine了、但是transmission 被鎖了P 不讓我轉RND、我為有關上engine再從新打著engine , 終於可以打著engine及可以轉去D了、但是engine light on , 之後同一天去 了幾個地方關了幾次engine也可以打著engine 、回家後我關了engine等了兩小時、再打著engine 而且engine light off 了。 請問一下為什麼會怎麼樣？ ？ 第二我上綱看過有人說如steering lock壞了也是打不著engine、不過是連kick kick 聲都不會有、而且返車行整要$2700加元很貴的、請問一下李sir會不會教學 換steering lock motor ??? 因為換motor不用program 是嗎？ 我是想問以上兩個問題,謝謝,

[@myalt1936]

same problem with my 2010 GLK 350 causing intermittent check engine light with minor evap leak code with mechanics smoke testing for hours finding nothing....I already know this it the problem, just trying to figure out how to fix it without $1300 for a new fuel pump and filter I know the dealer will tell me to replace.

[@simonhowes8987]

I have a 2007 E350 and I located the 2114710179 Seal ring but the other part 2110470110 is not compatible with the 2007. Any suggestions?

[@LeighSr]

The most accurate way is to look up the part number based on the vin number.

[@XLPerformance666]

你好，我是w218 cls550 车主，车厢内有汽油味很久了，无论油箱满不满，开的快不快都有，今天我趴在地上看了一下，车的左侧下面在滴油，闻了一下确定是汽油，请问你知道这是什么问题吗？ 谢谢

[@LeighSr]

您好！ 这是很严重的问题，可能是油管接头渗漏，甚至是油管破裂，不要尝试自己修复，尽快去dealer修理，这个符合15年的emission保修。

Evident of poor built quality of Mercedes car, for my W211, we have spent > USD1800 to overcome this gas smell issue. Dont buy Mercedes, period. Go for more reliable car.

[@LeighSr]

Actually, this problem should be covered by 15 years emission warranty.

[@mahadimahmood659]

@@LeighSr I never had this gas smelling issue on my 20 years plus Ford, not on my Toyota, not on my Honda. Only lowly engineered car will face this low tech engineering.
