I have had a couple of cars over the years that had a see through plastic filter in the engine bay and you could readily tell. The MB filter is metal, even if it were clear it is tucked away along the right rear frame in the rear seat region.

Do not go past 60k with the filter change

Of course there's a way to check if the filter is dirty. Just open it...:D :D :D
This filter had about 70k miles in it and the filter element was covered with dark grey gooey. Not blocking the fuel flow but still the filter was past due change.

If you just follow a routine maintenance schedule--A & B Service--your dealer will know when and what to do, and you will not have to worry about it.

$120? Did your dealer tell you that? If you have your car serviced according to the MB FSS, I believe they routinely change the fuel filter at the 60k mile B Service, but I have no way of teasing the cost of that one small item out of the overall cost. Also, I would never put a Purolator anything in my MB!

I wouldnt use a purolator either, the MB fuel filter has the fuel pressure regulator built into it, that is why there are four hoses instead of two. I want to say the oe replacement was a knect (sp?) and it was only about $35. You also need four new clamps.

This unfortunately seems not always be the case. My car had 70,000+ miles on it when I got it and it had been serviced by authorized dealers. But the fuel filter had never been changed:mad: . How do I know? Easily, the clamps on the fuel lines were originals.

(Of course it might also be so that the previous owner had declined the change. But whatever the reason, better check yourself whether the filter has been changed or not.)

Only three clamps needed, the fourth breather line (smallest) going to evap canister
does not need a hose clamp.

Use clamps with flared edges only, they are friendlier to the rubber hoses.
