    The value of dual fuel filters

    The pic below is of the filtration elements from the two fuel filters just taken off my car. Standard factory type (Ryco Z332) on left, & the CAV type filter element I fitted as a pre filter on the right.

    Both had been fitted at the same time about 12000kms ago, including our recent 10,000'ish desert trip.



    On this basis I think in future I will change the pre-filter every 10,000kms & the standard filter every 20,000

    Neither filter had any water in them.

    Cuppa what micron are you running for your pre .I've just finished doing mine about a half hr ago and am running 30 micron in a filter water separator in a fuel manager unit .Went the whole hog and installed a primer bulb between tank outlet and filter which allows a quicker bleed of both filters ,the bulb is 10 mm or 3/8 brand Scepter marine p/n 05869 and got it from Road Tech Marine .Not all bulbs are diesel suitable .
    U have 4 choices in life :U can like it; lump it; love it or shove it, take your pick and stick to it !

    They are the Delphi version of the CAV type glass bowl filter, bought online from Ebay/Wagga Tractors. Delphi 296. Depending on where you look they are either 5, 5.5 or 6 to 9 microns!
    The diesel in the glass bowl had a fair bit of fine sediment in it, whereas the diesel I drained from the standard filter was very clean.
    Fitting the primer bulb is probably one of the best mods anyone could make I reckon (IMHO). I also fitted one when I fitted the CAV filter (I copied Macca) & it makes priming SO easy compared to those silly short stroke pumps on top of the standard filter. Would be worthwhile even without the pre-filter. I also found that not all primer bulbs were rated for use with diesel, & shopped around until I got one that was.

    If I was fitting the pre-filter again I'd consider putting it on the passenger side of the motor, even though it would significantly increase hose lengths, only because accessing it where I have it is a bit too squeezy, making the task of replacing the filter element & re-bolting the assembly back together a bit of a juggling act. I suspect that if I ever need to replace a filter element out in the desert it will provided sufficient motivation for me to move it when I get back home.

    Must have copped some dirty fuel on your travels there cuppa. I only have the single fuel filter, but I change mine every second 5k oil change regardless. Probably not necessary but I call it preventative maintenance....

    Yep, that red dust gets in everywhere, I think you have to expect it & prepare for it if heading out into the outback.

    Primer bulb arrived today, big sucker of a thing, so I think I will have to add a bit more fuel line pre the fuel filter to create a loop big enough to fit the pump plus my hand to operate it.
