So - this is my first post though I've been using this site for over a year for my first Mercedes 300D, and it's pretty sad. I have been having fuel starvation issues, or so I thought, ever since I got back from a road trip to Portland, OR - and finally tracked it down today - my fuel tank has collapsed - oh no! The car is actually running great and there were only a couple of little issues I had in OR - but everything was running great once I got back to CA. The posting from boneheaddoctor (link below) shows exactly what happened.

So I have a couple of questions - 1.) can this happen from anything other than a clogged vent? My mechanic said he blew this out right before I left - but he did say there was rust in it. Could he have blown rust into the tank and then the rust could of clogged the supply line???? 2.) Can you salvage a sucked in fuel tank - or am I screwed and have to replace it - along with a fuel sending unit!!!? I've already taken it out when I first got it and cleaned it all up, replaced the tank screen, so I can replace it myself.

Any ideas out there - I appreciate your help,

Also - I know when it happened and realize now that the tank was sucking in air upon opening the fuel cap - I just thought it was the increase elevation. I didn't know this could happen - I am new to all of this. Wish I would have looked at the below link earlier!
