Hello members,
A recent trip I encountered problems with contaminated fuel.
Loss of power not being able to get more than 1800 rpm out of my 2002 Nissan Patrol 4.2 litre turbo diesel engine.
A change of fuel filter did not fix the problem.
A phone call to
Fremantle Fuel Injection and they gave me a fix to get me over the problem.
Remove the 17mm bolt on the inlet to the fuel pump, swing the pipe out of the way, taking care not to lose the two washers, top and bottom.
Using a thin piece of wire with a hook on the end remove the spring and then the fine gauze filter below.
Clean out the filter, I used petrol, then refit.
Cleanliness is paramount so ensure you wash any dust and dirt away from around bolt before removal.
Diesel fuel can be contaminated by a bacteria that passes through your cartridge filter but is halted from entering and destroying your very expensive fuel pump by this gauze filter in the fuel pump.
Have now bought some "Liquid Engineering-FUEL SET-Fuel System Conditioner" and will add it at a rate of 25ml per 100litres of diesel to clean out the bacteria.
Photo attached to show you the 17mm bolt to remove.
Failing the very welcome advice from
Fremantle Fuel Injection I faced a very slow 350km trip to the nearest major centre (Kalgoorlie)
Hope this advice may help any of our members faced with this problem.
**** Foot note**** With out mention of service station involved with supply of fuel I encountered the same problem on return journey to
Perth.
Was an easy fix to get me under full power again.
Auriferously
Nightjar

It seems contaminated fuel is more common now as I have had to replace a pump at great cost on a GUII 3.0 recently.
It seems that less than honest servo operators/owners ar buying the dregs or contaminated fuel and selling it at a discount to mugs.
I for one will now only buy BP, Shell,
Caltex at large servos and truck stops. This will not totally prevent getting bad fuel as sometimes a bad bit may slip through.
Of course the addition of a biocide and fuel conditioner now is essential. I will be also changing fuel filters a lot more often as the cost of a fuel filter in the big picture of things is miniscule.
Nightjar I am glad you were able to get home and I am sure
the tip you have given will help others in the same predicament.

as for cleaning the filter, this should be changed at regular
services as per nissan schedule. it is often overlooked by many, especially those who do home servicing.

Morning Donks1,
The s/s gauze filter in the fuel pump, mentioned here, is not in the Nissan service schedule.

Thanks Nightjar - have copied and saved your 'ingot of inestimable value', for future reference. Although almost indestructible, our 4.2 GU is still subject to the vagarities of fuel purity.

Hello Keith,
Going back to my old MQ Patrol, the full Nissan workshop manual did not mention this inbuilt filter in the fuel pump. Although this one was accessed by removing a bolt underneath the fuel pump. One Fuel injection outlet had already convinced me the fuel pump was u/s and required an overhaul. When simply it required a filter change, a big saving of $$$$$$. Never had a problem with the following GQ however I would suspect there is an inbuilt gauze filter in this model as
well?
Makes me wonder how many unfortunate soles have paid out $k's to unscrupulous operators under the pretence that the pump required major work?
Regards
Nightjar

Hi all,
I removed the gauze filter (blockage) entirely from my 4.2TD and fitted an in line fuel filter. Easy to see, change and will not block as easily.
