    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

petcock screen question

I am rebuilding the original petcock from my 86 550es. It is in amazingly good shape. My question - the screen has a small hole at the top (see the hole circled in red in pic below) and it seems as if this hole will allow unfiltered fuel into the petcock. Anyone have one they can look at? I'm inclined to JB weld the hole shut - the rest of the screen is like new. thanks

I'd leave it. Since that part looks to be in good shape most likely that hole is intended to be there for some reason.
 
i looked at it some more and thought about it. only explanation i can come up with is the hole is there to pass fuel if the screen becomes completely clogged
 
Not much to worry about if it is going to bug you run a sheet metal screw in the hole.
 
leave it be if it looks factory then its not an issue..And a sheet metal screw!!! How about you go for something more practical, less heavy, and non corrosive like a nylon screw...
 
not worrying. just seems odd to have a hole that can pass unfiltered fuel in such a fine mesh screen. i've rebuilt hundreds of fuel cocks and have never seen a way for unfiltered fuel to pass like this one. thanks.
 
dont add anything metal that can rust directly into the fuel system EVER!!!!!thats the purpose of the screen to stop METAL rust chunks and silt from getting downstream..
 
A screw head won't fit through the hole in the tank either. So there! Yeah a plated screw around all that raw steel inside of the gas tank dangerous.
 
i'll probably leave it alone. I used to be a fuel systems engineer and was just looking for the cool tech explanation. Good idea to run a small inline filter anyway
 
In my limited experience, the rebuild is a waste of time. Buy the new OEM petcock...it's worth it.
 
hmmmmmmmmmmmm. alway had good luck with the new diaphragm and o ring kit.
