About 2 months ago my 'tour wouldn't start. Suspected the fuel pump. Towed to dealer. Dealer can't find anything wrong. Car started immediately for dealer. Figured the tow jostled the gas around a cleaned the strainer enough to allow it to work. Since then the car hesitated and behaved oddly below 1/2 a tank.
I have ESP warranty, but $100 deductable. For grins and giggles, I figured I would try to save some $.
Today I pulled out the back seat, cut open the floor and removed the pump. The round strainer was dirty (Not completely clogged) and the pump strainer was very dirty too.
I used an orange based solvent, cleaned the strainers, cleaned the "cup" the pump sits in. The o-ring sealing the top was stretched and wouldn't fit. I cut about 1/2" off and crazy glued the ring together (with a high performance German made glue). Re-assembled, Duct taped the cut lines in the metal underseat area, and test drove. No hesitation and the off-the-line performance was much better.
Note: If you attempt this be patient. It took a while to get the lock ring off (cut myself, blood lubricates well), and you will need a new O-Ring if you don't have the benefit of German Adhesive Science.
I wouldn't of attempted this without the benefit of seeing that another CEG'r had done it and explained it. Thanks to those who explained it and pictured it.
