The only reason I ordered one from the dealer is that I have already tried one that cost around $2.50 from ******** Az, which was very different (i.e. cheaply made) than the OEM Mercedes gasket. The OEM one has a lot more solid rubber that fits like a glove and is fuel resistant (I have one in my 240 parts car that's still in good condition). The ******** one is very thin and does not seal well, melts with VO and already cracked in less than a year.
