Had to replace gas tank! Percolating/gurgling noise.

I started developing a gurgling/percolating noise from behind the passanger seat area. I was told that it was the accessory fuel pump that was making the noise. Apparantly now there is a fix but it involves replacing the gastank.

Anyone else with this problem?

I changed the tank, but there is no fix. You get a different sound. This time its more like a spraying sound. I think the gurgling was better. Just ignore and blast your stereo

This was a well known problem on the 03's and some 04's. AMG did a run of new tanks just for this problem. I have an 03. Got the new tank after lots of screaming (took 6 months, waiting on a manufacturing run).

Problem solved 100%. Do a search on this forum. Lots of stuff on this from around a year ago.

Covered by warranty. Almost a week for the whole job. Not a small task.

If you haven't already done it search the forum for past postings on this. Many details.
