Does anyone know the O-Ring Specifications (Diameter and Thickness) for the replacement O-ring for the screen located under the Fuel Tank. I have not pulled the screen for cleaning yet, but would like to replace the O-ring while I am there. I have a selection handy and am trying to avoid the wait of ordering one from our friends here @ Mercedes Shop. I will order one tomorrow if I can't get the size specs to check my against my coffee can collection.

Also any advice on clearing/cleaning the fuel lines would be helpful. I plan on breaking the line in a few places and blowing them out with compressed air.

Thanks in adance.
