I've searched the archives for a posting I vaguely remember. It concerned a 560sl that was very hard to start when the engine was warm.

The posting mentioned some kind of a relief valve for the gas tank. I cannot for the life of me find that posting.

Can someone refresh my memory? "IS" there a relief valve that's very cheap that will solve my problem. At time... I have to try three times (cranking 8-10 seconds) before my '88 560sl will start. Yes... this happens when it's warm.

Thanks!
