幾乎沒辦法更換的原因在此,另外一邊的油封是否有脫落,也無從得知.
另外我昨天晚上在這個MB知名美國論壇看了一晚,這一篇討論將近九頁.結論也是一樣.所以無解.
最有價值就是這篇發表:
I don't know for certain if the OP has a metal or plastic tank, but it sounds like he obviously has a code 917 vehicle.
That means it's a Partial Zero Emissions Vehicle (PZEV.) The fuel systems on code 917 Mercedes have to be 100% sealed. And the gas tank cannot emit any gasoline fumes, period. The usual plastic tanks made of high density polyethylene (HDPE) that Mercedes has been using are not PZEV compliant. So it's very possible they used steel instead to make it PZEV compliant.
In fact, the industry has been arguing about this and the steel lobby says PZEV plastic fuel tanks cannot be built cost effectively. However, Mercedes just signed a new contract last year for newly designed PZEV compliant plastic tanks from a vendor in Michigan, TI Automotive. TI Automotive Earns Largest Contract in Company History :: TI Automotive
But those new TI Automotive PZEV plastic tanks weren't available for the 2009 cars. So to be PZEV compliant, Daimler probably had to use metal fuel tanks that are fully sealed and PZEV rated. "The vehicles constructed to meet the PZEV requirements must achieve both SULEV (Super Ultra Low Emission Vehicle) exhaust emissions and zero evaporative (fuel system) emissions." The PZEV category was recently created as a bargain to postpone ZEV requirements (zero emission vehicles.)
Here's a note for OEM fuel pumps that I saw on a Peachparts Mercedes DIY posting: Notes: Assembly includes Fuel Level Sending Unit : without PZEV Emissions (917) For Vehicles with Code 917, the fuel pump cannot be serviced separately only the whole sealed fuel tank can be purchased through the dealer.
So the issue here is that the OP has a code 917 vehicle. And it's very possible that many of the 2009 cars were code 917. And they have sealed systems and steel tanks. And if the PZEV plastic tank contract was just signed last year, then the early W212 cars may also have the same set up.
給各位參考!

要不是已答應德訂貨,真想送到台北改裝3.2萬搞定,且下次再壞只需換幫浦1萬搞定,也不用等半個月呢!! 為啥樓上只需7萬呢?
