    Default Extra fuel filter

    Is there a way that one can install an extra filter (plastic ones) in line with the existing diesel filter to try to prevent dirty particles going to the diesel pump? (3.2 diesel)

    Chris, try searching "UDF filters". There was a million page thread, with plenty data, on the subject.

    Hi Chris.
    The plastic one you see in midas etc are generally for petrol vehicles which don't need as good filtration as diesels do, I don't think it would help as it would let most of the damaging stuff through.

    I am looking also adding an extra filter to my DiD, I have bought a Gen 3 with the non common rail motor.
    The OEM filter (replacement is a GUD Z554) does 7-9 micron filtration, I have found a filter holder CF16 and GUD Z314 filter that does 3-5 micron with water trap that I am going to install after the OEM unit. Will cost with all fittings and hoses just over R500.

    The udf filter, as I understand it, is more suited for the common rail motors as it filter to 2 micron, and making it quite pricey at over a grand for filter plus holder.

    UDF filter is first prize.

    But a good alternative is to install a Racor or Donaldson with water separator.

    I have installed a Donaldson filter with water separator. It is not just dirt that damages a diesel engine

    Hi Chris, I see you have the same motor as I do.
    The Toyota d4d common rail motor and mitsubishi DiD common rail motors need much higher filtration due to the tighter tolerances and higher pressures in the injectors so I would also agree with using a Donaldson, racor or even Udf 2 micron filters.

    I think it is overkill in our older generation diesels (although there is no such thing as too much filtration!) , that's why I am going for an extra in-line 3-5 micron filter as recommended by Tim at the GUD filters technical dept after having a long chat to him and saying I wanted some extra protection. He says the standard filter is already very good, in it self as being a 7-9 micron filter which is better than the newer toyota d4d 10 micron OEM filter...

    Racor or Donaldson filter are cheaper and are more readily available

    Thanks, I will then follow up with Donaldson, just spend R24000-00 on diesel pump end injectors so want to minimize the risk of dirty diesel
