I change the inline fuel filter at least 3X yearly due to clogging, and at least annually for the main filter, regardless of mileage. Cheap fixes. On 11/13/06, Kaleb C.

[MBZ] Fuel filter changes
How to tell; my 300D started slowing down to about 45 mph top speed i turned off to check filters; yes i have most all parts to fix car in OTHER CAR!!!; I did remove main filter dump out; then clear pre filter; had black specks all around inside: i shook blew thru it enough to get home w. no more loss of power; OH! the night before i had removed the tank screen cleaned checked not bad at all; then i stuck my finger up in tank rubbed it all around to loosen up a small layer of sludge; only felt like thin layer???then the sludge went to pre filter, never had a pre filter so stopped up! hadn't had this car for long; changed repaired a lot of other items, but did not change the CHEAPEST?? the pre filter; i have used diesel additives also in tank; Steve
Re: [MBZ] Fuel filter changes
Not really worried about it as I think my car has reasonable power for its type. Was just curious as to whether there were obvious symptoms I should keep in mind as this is all fairly new to me.

Re: [MBZ] Fuel filter changes
When your car starts having less power. The first time I experienced it with my 83' 300D, the top speed on the highway dropped to around 65mph, and trying to climb hills was at a significantly reduced speed.

Re: [MBZ] Fuel filter changes
Yes-even on my 240D I could feel the loss of power-esp. under load. (Imagine that.) I have also been able to see the little black flecks in the clear inline filters-less so in the translucent ones. On my 300D 2.5t it started to miss at speed-just before the turbo kicked on. Marshall is right-change as needed-but I carry some spares in the trunk of both of mine.

On a diesel, the result of a clogged filter is merely a loss of power, no harm comes to the engine. Leaning out a gas engine, on the other hand, can burn a valve or fry a piston. I always try to carry a spare filter, as one bad load of fuel can clog a filter, even the day after you change it! I change mine at about 30,000 miles and have only been slowed once on a trip, in over 500,000 miles of diesel travel. Regards, Jim Friesen Phoenix AZ 79 300SD, 264 K miles 98 ML 320, 146 K miles
Re: [MBZ] Fuel filter changes
I would say overkill. On a diesel, the result of a clogged filter is merely a loss of power, no harm comes to the engine. Depends on the diesel! The non- common-rail 24-valve Cummins motor used by Dodge 'twixt 98 and '-2 (?) would eat the injection pump if the fuel filter clogged. It has a rotary fuel-lubricated pump, however. -- Jim
