Hi all,
I have a problem with water in fuel filter, i have a 2005 patrol GU 1V turbo, the problem is most noticeble when towing my van, malfunction light comes on, so i drain a bit of fuel out of the the filter, guessing any water will drain out first, this fixes the malfunction light , and sometimes fixes the problem with sluggishness , other times and it seems to be more often now the power is just not there,
do i need to drain the fuel tank or someone said if i take the battery lead off and put it back on, this seems to work.

Any suggestions
Thanks

I dunno a lot about the 3.0 but have the filters (fuel and air) been replaced regularly, thats always a good start.

Could be water in the tank, there doesnt seem to be a drain plug on the tank, but the problem only really arises when under pressure like when iv'e been towing the van for a couple of hours

I would assume that once you have drained the filter you prime it back up. It sounds as though it may be pulling air in from somwhere which if only a small hole or something is allowing it then will be more noticeable under load. Try the search about priming them and air in the system it doesnt have to be anything big ( a pinhole will do it)

Thanks i hear what your saying ,yes i do prime fuel back into the filter after draining, but would the water malfunction light come on if it's a air problem.
i'm open to all thoughts

Many thanks

Possibly I think the light will come on if there is a filter restriction water etc i am not entirely sure about air though.

What does the filter look like when you replace it?.
don't want to be alarming , no algae is there?.

hi Kimbara
Just have a quick look at your fuel tank breather and make sure its not blocked. When it is playing up open the fuel cap and listen for air being drawn into it. Thats my first thought. When you drain the fuel filter next drain it into a glass jar and let it sit for a while, if there is water in it you should see some separation also as Robo said in could be an algae bug in the tank ,look for a blackist ring on the jar.
hope this helps

Do you get water out of filter when you drain it???? If so try putting about 500ml of meths in fuel tank as there appears to be no drain plug, the meths will absorb the water and mix with the fuel, next time you change your fuel filter, pour the remaining fuel into your hand to see if any water comes out and what colour it is to determin if tank is rusting.

there are diesel fuel additives that can be bought from repco and other semi reputable auto parts stores. many of these have anti algae ingredients, many also have water absorbing ingredients. give a slight overdose to your take, it will help clean out your injectors, fuel lines, fuel pump, tank etc and is an easy first step
