This is my second post on this and Im hoping for some good advice!

1992 300D I have fuel leaking from the filler cap....but its not the cap
Mercedes tech says that the filler neck entrance is messed up from the fuel nozzle hanging down on each fillup...this is a normal occurance according to MB tech

Can this be repaired?
Or do I need to buy a new tank


Thanks in advance
Wayne
