Thanks! I'm not going to install drag-pointer restriction gauge on my MB just because the MB filter (30-micron) should have much less restriction than the VW (5-micron) and the fuel flow rate on the MB is much less than the VW. The VW uses less fuel of course, but it relies more heavily on fuel to cool the injection system - so in the VW fuel that's not injected passes through a fuel cooler and returns to the tank at a relatively fast flow rate (compared to the MB).
And, if you go with the 6" replacement filter restriction will be even less...
Cheers!
