  • 2nd filter or Water Watch

    Hi all,

    I've read with interest the posts regarding fitting a 2nd fuel filter to the D4D.

    In short, most seem to agree fitting a Racor 200 series or 400 series filter with either a 10 or 2 micron filter before the OEM filter seems to be the goods. These combinations ensure good fuel flow rates from 45 GPH to 60 GPH which is more then enough to keep Mr Toyota happy and removes both contaminates and water.

    What I haven't been able to find is any discussion regarding the Water Watch system.

    So my question's,
    What are the pros and con's between the two systems?
    Those with Water Watch, are you happy with your decision and why?
    Would people be happy to post photos of their installations for us DIY guys and girls to cheat from?

    Regards

    Water watch does not filter particles from fuel. I hear it does a great job of trapping water though.

      I am speaking with them at the moment. Looks like around $500 for the kit and $95 for the mounting bracket set up. I like the idea of this unit and a new one will be fitted to my new truck as soon as possible.

        Hi,the racor 400 series does come with a water sensor and alarm as an extra but better still as the bowl on the 400 is pretty deep you should see the water build up before it hits the OE filter which also has a water sensor and alarm Cheers Foxy

          Hi,
          I have just purchased a Prado 150 update (4th Sept build date) and feel in a bit of a dilemma.
          After reading many posts here I know I need to protect my fuel system better as one bad diesel fuel refill could well be a disaster.
          As a result I am considering either a :-

          1. Watch water system which should avoid any Toyota warranty issues and change the Toyota fuel filter at every 20,000
          km. (note: there are Toyota dealers who are Water Watch distributors) or,

          2. Installing but less appealing a Racor 230R fuel filter using 10 micron filters changing them at 20000km but running the
          risk of Toyota not supporting me if I have a fuel system claim.(pump, leaks, injectors etc...) I have a 6yr. Toyota factory
          warranty.

          The new upgrade model (after 26th Aug. 2013?) I think cannot fit either in the usual place next to the Toyota fuel filter as there is now a 'relay' box in that place! (which may not be able to be moved?)
          I have discussed this with 'Water Watch' and sent them some photos of the area and are waiting on their thoughts as I believe their Prado bracket they supply won't now fit and anyway it couldn't be located in the usual spot due to the Relay box.

          So I am at a bit loss with all of this and would welcome your current thoughts on:-
          1. Should I have an extra 'filter' of some description or am I over reacting?
          2. Is water the main issue with bad fuel?
          3. I am leaning to Water Watch due to the ease water can be removed and Toyota warranty issues - best compromise?
          4. Are Water Watch customers happy with its performance , quality etc..?
          5. Any new 150 Upgrade owners been able to fit the Water Watch and where?,
          6. Maybe use a 'Mr Funnel' filter as added insurance in places a long way from home if I fit a Water Watch or am I again
          overreacting?

          I hope this all makes sense.
          I would love to hear from Water Watch owners and anyone who has a thought on these issues and can point me in the right direction.
          Thanks in anticipation
          David

            Gday Bluedog16

            Oooooh! ... This could be prickly!!... Lol

            I will explain in layman's term's so that you will get a better understanding without going too deep but it will be a long read!!... Lol

            Your main enemy is WATER!

            I do believe that when Denso designed there system's that they did know what they was dealing with and knew that apart from foreign particles in fuel is very bad they also knew that the fuel filter had to be capable of stopping particles that where larger than the actual injector tip size!!... The 10 micron filter does stop particles that are larger than the actual injector tip size! ... Whooooo! .... Now that changes the picture doesn't it!

            Now knowing this it is apparent that the "Next" enemy that is very abrasive to high pressure injectors apart from foreign particles is the number one culprit which is "WATER!".....

            Water is highly abrasive at high pressures.... Causes premature wear of the injector tip and corrodes critical and sensitive parts!

            Your stock standard fuel filter also has an in-built water trap along with a float built into it to warn of water build-up in the filter! ...

            Given that water is heavier than diesel water will collect in the base of your stock standard fuel filter and when/ if water is collected the "Water float" will rise and trigger a warning light on instrument panel!

            Unfortunately this does not always work but is also not the end of the world.

            Typical Scenario's Of Water Contamination!

            #1 water will condensate in the fuel tank when warm fuel is cooled rapidly in a cool environment.... EG: fuel recirculates back into the fuel tank after passing through the injectors and common rail and on long drives this eventually heats the fuel in the fuel tank and this also is how the injectors become liquid cooled along with the oil that is submerged around the injector it's self under the cam-cover!

            #2 you can grab as much as 1 to 2 ltrs of water in one gulp if you are game enough to fill your rig with fuel whilst a tanker is dropping fuel/or just dropped fuel into the servo main tanks!!! .. Tends to disturb silt and water as 250k (or more) fuel is dumped!.

            #3 buying fuel from an old servo (Usually outback servo or old independent servo) that doesn't get a regular fuel check for dirty tanks!

            #4 buying fuel from a servo that does not move much fuel (Not have a high traffic flow or looks old!).

            Now with the a better insight of the different ways of getting bad fuel a simple glass water trap bowl you can visually see if you have water contamination and can drain it just the same way as you would with the inbuilt drain on your stock fuel filter but have the edge of seeing if you grabbed bad water with the glass bowl!

            The other advantage of a glass water trap is that its cheap and "DOES NOT/ WILL NOT" restrict fuel flow or increase negative pressure on the fuel system!

            Negative fuel pressure increase will not only make your injectors respond slower it can also make your fuel pump noisy!

            Now either you go duel filter's or just a glass water trap is strictly your choice but that "IS" basically a reason for upgrading your fuel system!.. It is the water!!

            Cheers

              Forget about a primary filter and fit a water trap, if you can afford it fit one with a sensor and alarm.

                I agree with everything you said mate except for this.. 250,000 liters of diesel in one truck? That would weigh over 200 tonnes..

                  Thank you Skywalkerrun for the effort and time you went to in your reply -very much appreciated! And also adrian5800 for your support.

                  You both have been very helpful and I will now focus on a Water Watch system if it can be made to fit on the new update 150 model.

                  I would welcome any comments from anyone who has installed a Water Watch system about its effectiveness, quality etc....

                  thanks David
