W208 fuel filter

[tacho d]

Hi all, about to order a fuel filter for a clk 230 and supplier wants to know if it has one pipe in and one out or 2 in and 2 out. It is a 2000 onwards example which leads me to believe it is the latter. Reluctant to remove the tray until ready to fit filter. Any ideas?

Get one from Mercedes if you are not sure. They are not expensive.
