  • extra fuel filter

    Has anyone considered a extra fuel filter system such as a CAV 296 with a glass bowl at the base to help capture water and solids especially when touring the outback ? I'm considering it for my 150 SX only for extra insurance over and above the OE filter .Being an ex farmer and using such tractors and diesel vehicles just asking that's all :roll:

    Re: extra fuel filter

    I fitted one which is along the lines of a cav filter to a 120.

      Re: extra fuel filter

      Pedro, Mate I have looked at a CAV system and their filters go down to 5 microns, that's the 262 .Someone has also said that because of the extra filter, it may put extra strain on the sensitive common rail system in the latest d4d . I'm not sure what to believe because it all depends on who you talk to . I like the idea of extra insurance especially as there is so many differences in Diesel you buy out back and also in the city . I like the idea of a warning system but I can't afford the cost but I can add a system using Cav parts ie the glass bowl, Cheers

        Re: extra fuel filter

        sorry to alarm anyone, but any restriction in the fuel system... ie an added fuel filter, will void your toyota warranty, they need to flow 20-60 lts per hour in flow rate, putting a fuel filter inline restricts the fuel and causes damage to the fuel pump... currently to do a pump and injectors on a D4D inline 4 cylinder engine costs around $8K... Cooma diesel have a nifty device that will solve all your problems, give Dave a call at Cooma diesel. :roll:

          This has been done to death on other forums. I remember posting here about the filter that I fitted to my last vehicle, and was shot down with the same arguments. I have done plenty of research lately, and the consensus is that a 20micron filter before the OE filter, and then a 2 micron filter after the OE filter is the way to go.
          Reason for 3 filters is that new elements do not filter to their advertised specs until a few hundred kms after they are installed. The three filters allows for a staggered maintenance regime. The 30 micron filters out any rocks, the OE filters down to 10 micron, and then the fuel goes through the final 2 micron filter giving the best fuel quality possible.

          The issue of fuel supply restriction has been done to death as well. Shop around for filters with a high flow rate. There are Raco 445 filters available from http://www.westernfilters.net.au for $350.00. That is what I am doing, and it comes out at the same price as one water watch system which only looks after water contamination, not abrasive debris. The Raco units have flow rates of about 170 litres per hour, which means your fuel system diagnostics will not notice a thing.

          This is what has been recommended for all D4D engines running in South Africa, where apparently the fuel can be suspect at times. There are several reports of this system working well in vehicles that have traveled over 150,000 kms. I have read that TMC Japan has endorsed the recommendation. On another note, I don't think that the CAV systems as noted above, have a decent enough flow rate. They are cheap, but all of my comments above are regarding the more expensive Raco System.

          Good luck. :-)

            Re: extra fuel filter

            Further to my post above........ The CAV filters as mentioned earlier in this thread, have a flow rate of about 45l per hr, which is not sufficient for a prado 1KDFTV fuel system.
            Anyone considering this type of installation MUST be aware that they need to install a sytem that has a high flow rate.
            I would go for double + >50% of fuel delivery and pump lubrication/cooling requirements to be sure.
            Filters loose flow performance as they clog up with debris. This has to be taken in to consideration when selecting the system for your vehicle.

              Re: extra fuel filter

              the problem is not filtration of particals... is water that's the killer, micron... smicron, dosen't matter how fine you filter your fuel you will never stop water, the problem accurs when the water passes the pump (toyota filter will not stop because its a sediment filter) and starts oxidization in the coomon rail, which is between the pump and injectors, then the cast pourous rail rusts and contaminates the denso injectors... I manage 70 toyota vehicles and am a deisel mechanic who has recently found out the hard way of what water can do to a toyota common rail fuel system, Water Watch by cooma diesel is all you need.the toyota filter is perfect but dosen't stop water, don't waste your money with other filters and have toyota reject a warranty claim.

                Guys....I've found this topic interesting reading as we have just purchased a 150's D4D ourselves..... I've got a cousin that works in the Filtering Business as he has had quite a few people coming in that have the Common Rail Diesels engines and have experienced problems with various forms of dirty/water in fuel resulting in costly repairs..... His advice was to install a 2nd Filter inline.... the Racor 230R Filter. Apparently, not only does this filter down to 2 mircons but also the filter contains a "special form of filtering paper" that will not let water penetrate through with a success rate of 99%, along with having the associated visable water trap as well, plus has a flow rate of 114litres per hour.....He has sold many of these filters and to date has never had any customers come back complaining.....
                This is probably what I will be fitting and according to Mr Toyota, will not void my warranty.....

                cheers...

                  We use a 0.5 micron aftermarket filter (installed after the OEM filter) here in South Africa on the 3.0 D4D without any pressure/supply issues. Because we travel a lot to our neighboring countries (e.g. Namibia, Botswana, Zambia, etc.) you never know what quality fuel you get. The filter system is from these guys, http://www.udfiltration.com/

                    Re: extra fuel filter

                    I just bought a 45 litre/minute Mr Funnel from Amazon. I figure, why put the crappy fuel into the tank in the first place?? You simply fill the tank via the Mr Funnel and it prevents water or floaties from entering the fuel tank. The down side is that it is reasonably bulky and has a short spout. I am just going to add some tubing to it to extend the spout and will store it in an ice cream bucket or just strap it to the roof rack. Unless I am away I always fill up at the same servo with BP ultimate and keep receipts, so I will only use it when filling at other servos or on trips.

                    No warranty hassles from Toyota and considerably cheaper than the second filter option. I may look like a tool when filling up, but I don't care if it saves a $10k engine and prevents a breakdown in the middle of a desert.

                      I've had one of these installed for the past few months and "according" to Toyota, I should have no warranty issues...... but I don't know about the price for replacement filters being that cheap....I've been quoted a lot dearer than that, especially for the ones that contain the special paper that prevents water from passing through......

                      As above, the Raco 230R filter is probably the way to go. Position (install) the filter before the gen. Toyota filter system. This will stop any water getting through to this area and prolong the life of the gen. filter. As mentioned above the flow rate is correct. It will probably be the best $300.00 you spend on your 150 series, as the repair bill for this type of damage is $3500.00 to $5000.00 depending whether you need a new supply pump. The filters for the Raco (Parker) is about $5.00 to $10.00 each. No more playing a game of cat and mouse inbetween Toyota and the fuel companies once you install this item.

                        Hi Rob,
                        a couple of queries:
                        1. did you install your 230R before or after toyota's fuel filter?
                        2. did you have any mounting or installation issues?
                        3. how often are you intending on replacing the racor filter?
                        Thanks

                          Hi Rob....

                          I installed mine on the LHS back cnr next to the OEM Filter... very simple to install and it's plumbed b4 the OEM Filter. The one I have has a glass bowl which will govern how often I replace the filter element.

                              Yep, that's about what I was quoted and depending on where u go & fillup, it should only need replacing every 50>70k or so......
