Know that its been around a lot but more I read more I get confused with flow rates ect .So I have a 2007 Toyota Work Mate Cruiser obviously with the V8 Motor .
Question is any other members fitted a pre-filter water separation unit to a V8 Diesel and if so please what has been used and has there been any disadvantage by doing so like loss of power ,lack of fuel pressure
.I keep hearing //reading about fuel pump cavitation ,fuel restriction and the list goes on .I would prefer a pre-filter water separation unit rather than just a water separation unit if possible
Thank you all and hope some one can help with this
Terry

Terry, there has been many discussions about this topic as a search of the
forum will reveal. Threads 100706 and 100622 are good examples. I am using the Terrain tamer fuel manager filter system which is fitted after the factory filter on my 2009, 79 series V8 ute. I have had no problems with fuel pump cavitation, lack of power or loss of fuel pressure nor have I heard these stories on the
forum. My vehicle is also chipped and tuned to provide optimal power conditions when towing.
I have heard a lot of stories about contaminated fuel and the failure of the OEM filter to prevent water getting into the motor. I got a funnel full of crap from a fuel drum at
Well 23 a few years ago which would have been all but fatal to my engine had it not been for my Mr Funnel. That prompted the move to the extra filter.
Mine is aft of the OEM filter to let the OEM do its job as intended. The fuel manager is then the backstop.
Just ensure that you have adequate hose diameter at fitment and anywhere the pipe might pinch or bend when fitting into the tight Toyota engine bay, use the spring-wire hose maintainers.
Regards,
Mick

Hi Mick
Thanks for the “heads-up” on the Mr Funnel some time back; it got a good workout on the recent trip and not surprisingly, captured some crap from getting into the tanks.
I have the same Terrain Tamer filter (also your suggestion!) but mounted pre-OEM given it is 30 micron. My thinking was also it was better having the OEM as feeding to the engine in case anything ever goes wrong.
Is there a reason to have it the other way? Oddly, it was originally installed the other way around.
Cheers, Baz

Hi Terry,
I have a 2007 V8 VDJ79 Workmate ute.
I fitted a Stanadyne 2 micron with a primer-pump (fits on top of the unit), filter change kit (= flag pops up to indicate needs changing), and a glass bowl for $440 (trade, July 2012). I fitted it behind the main tank and it is plumbed in so that fuel flows through this one to the Toyota filter situated between the 2 batteries. No room under the bonnet for the second one. The other day I noticed the motor lacking a bit of power so I checked the flag and it had popped up. I keep records: it had filtered 2014 lts for 15,120 kms (=7.5kms/lt). The filter is easy to change.
Some of that fuel was bought at
Laverton,
Warburton,
Kiwirrkurra,
Carnegie and
Menzies on a recent desert trip (5,000kms).
I cut open the filter - it was black, but there was no sediment in the bowl.
Interestingly, in the service book there is no mention of when to change the fuel filter! I guess when the dash light illuminates. Though I'll probably never have to change it because of the Stanadyne. I bought it in
Perth from
United Fuel injection (no affiliation).

Well gents thank you again I did not leave the discussion after just gaining what info I could from you all.I had to wait on a couple of reply' s.One being from Diesel care ,after asking you all and communicating with them at ( Diesel care), it looks like the Stanadyne
filtering system will be the way I will go .I received prices back for secondary filter kitat $317 .00 plus $25.00 postage to Tassy .The additional water warning light is $230.00.Not sure yet but assume this is for the FM100 Series - up to 350HP Max fuel flow (inc. return flow) 300 Litres/hour.At least hope so not sure yet is the water warning light can be brought separately or not.
Thank you all again gents for both your time and help thanks
Terry

Yes the warning light can be bought separately, as I bought
mine separately. The light and bracket are quite big, so I cut the light off and soldered on a small LED and a Piezo buzzer as sometimes a light alone may not get noticed for a while. Having the separate buzzer I know that if it ever goes off I know instantly what is happening, rather than the generic buzzer for all the other things.
Cheers
Tony
