      hi scotty i got a mercedes 2009 with a M271 kompressor engine that we got some trouble with... the fuel pressure are 4.3 BAR and the pressure should be 3.8 BAR do you think that the filter mayby clogged up? i told the workshop that i wanted a new filter but they said that it was not necessary because it was a lifetime filter which i belive but they can clog up to

      kind regards

      I have a 511 dollar fuel filter. How? My Chevy Lumina was throwing a service engine light on start up. The reading said a bad plug. We changed the plug. Car ran good for a month. Then car threw light again....on start did this every week or two or three. So, new plugs, coils, nothing! Went to the dealer. They wanted to change fuel injectors. Another shop did not help. Neither suggested a clogged filter. So one day I decidrd to change the fuel filter. $11 bucks and 15 minutes. End of problem. Two shops that did not even think of after $500 bucks of repairs advice etc it was a fuel filter. LOL. BTW do not fill up your gas tank if you see the gas truck at that station filling the tanks. Go elsewhere!

    The problem these days is some mfrs are mounting the fuel filter on or near the fuel pump, and in some cases, requires replacing the fuel pump as it can be one unit in some models/brands. The other thing is if you use quality fuel it's less of a concern. I have 147k on my vehicle right now, and no signs of issues with the fuel system. Still pretty much get the same gas mileage as I did from day one. I do run super concentrated fuel cleaner through the engine though periodically, which I think has helped but I have not noticed any difference in fuel economy over the years.

    What happens when you have a car that wasn't designed to have a self contained filter, so in 23 years no mechanic ever repaired/replaced it. Only in the last year since doing services myself have I discovered it. Do you think I can find a "like for like" replacement. "No part is avaliable for your car model".

    My 1991 Nissan Stanza GXE is having a difficult time accelerating. I shift it into 1st gear and it takes a while to get up to speed. RPM's match the speed. It's fine on highway speeds but at low speeds it is very sluggish. Taking it to the shop tomorrow. Hopefully it's just the fuel filter and nothing else. :(

    My 97 Honda Civic had no check engine or other lights come on, just all of a sudden car would not start. Battery was fine but engine would not turn over so just took a guess that maybe it was the fuel filter. I changed the fuel filter and the thing started up no problem. It had been about two years since I replaced it earlier.

    Herko out of Florida sells fuel assemblies for Corolla for $125 with new pump assembly and filter sock. Replaced mine. Pump still good but changed filter sock. Found alot of foil tabs and cardboard round tabs from drygas and cleaner bottles. Sock was almost clogged with junk almost black colored.

    I bought a 2001 Camry with the 5SFE back in Feb. Driving to work this morning and I couldn't rev past 3k RPMs in second gear, going 25 mph. Engine light flashing. Car's got 400K miles on it, and the filter is the original one that comes with the car. That's probably what my problem is... Now I have to work on a street parked car.

    I have a 2012 Chevy Malibu and recently I was driving with only a quarter tank of gas. I was driving at a fast speed on the high way but as soon as I came to a complete stop, the gas pedal became unresponsive and when I pressed it, the car wouldn't move. Do you think it could be the fuel filter?

    a lean condition will NOT make your catalytic converter run hot. Catalytic converters will overheat when there is unburned fuel (rich condition) going out your exhaust - the catalyst will aid combustion between the unburned fuel and oxygen so it doesn't exit your exhaust pipe unburned - Hydrocarbon pollution.

    I have a strong feeling after replacing multiple parts in my emissions system and still having codes pop up that the fuel filter is at the root of the problem. 308K miles on the car, thinking I should replace the fuel filter now for the first time!!
