Hi,
How does the fuel filter pump work in the diesel 4.2 patrol's (GU)?? I'm guessing it's a piston type pump that you just lift and push down, I couldn't get the black plastic know to budge yesterday.

You basically 'lean' few times, then have to release the pressure screw (white butterfly bolt) to release the fuel/air, it doesnt come up 2inches or down 2inches, it moves about 1/3 a centimeter! if that....
Almost sounds like when you open a vacuum sealed
orange juice bottle that 'popping' sound.

Sorry don't get ya, lean a few times??
I can't get the black knob on top of the filter housing to move even a mm. Though there is no air in the line I just thought I'd see how to do it if I run out of fuel etc, does this make a difference.

Lean on it - push down on it. It is already in the 'UP' Position, you just push it down - but dont try and move it a foot, it only moves few mm...
Will try
mine again when I get home.
I actually think there is another thread on this round here, try searchin.

Gday Austravel,
How's it all going? My car is downstairs, but I could find out about the pump fairly quickly. Apart from that, all running smoothly?
Cheers
Chris.

trucky, is the pump on the GQ the same as the GU, I remember the black pump on top, but haven't taken much notice of the GU, think I'll go down and check...

Thanks guys,
Couldn't get past the idea it was in the down position. Now I get it! I'll have a look tonight I don't remember there being a bleed nut at the top. I recall a drain nut at the bottom with a bit of clear hose on but will have to look a bit closer tonight.
Thanks again.

I was the same, tryin to lift it up, I thought of a pump that would move 3-4niches.. Nearly ripped me fingers off.
Do you ahve one of the original glovebox manuals, that explains it.. i have a spare if you dont. $20+post.

Thanks Truckster, did the same thing I was fairly heaving on the little black knob. I'll have another look in my manual, I didn't see it when I scanned through, but it must be there.

on the GU they dont have a bleed screw like the GQ , remove the fuel outlet line and pump away until you get fuel into a jar normaly only need to do this when you change the filter for a new one, and as you all say it dont go up and down much only a few mm

Thanks theratt,
I've yet to change a fuel filter, hence my questions. The filter prices are a bit of a shock compared to my old petrol GQ.
Do you use genuine or are there cheaper replacements out there??
Thanks

i just go to nissan and get what i have to, i figure i am saving anyway as i do all my own servicing on my vehicle, if anything breaks its going to be my problem i know, but i have that many modifications my warranty must be nearly void, although i did get a new bullbar off mr nissan after
mine cracked, not without a fight though

Gday Everyone,
I use a CAV filter system first and then it passes through the original fuel filter. I do this as i see the genuine filters become quite dirty after 10-15000 k and they arte cheaper to change.

Hi,
I'd heard that the nissan pump can't handle a second filter inline with the orginal and it should be one or the other. Is this right or you've done something different?

Gday Austravel,
I have worked for nissan for 13 years and have not seen a problem with dual fuel filters. Most diesel specialists recommend 2.
Thanks

Yep, gotta CAV filter before the main. Drain crap out of it every couple of weeks. I still change the main every 10,000 though as a safe-guard as $20 here is cheaper than a donk re-build.
As for the pump - Push down twist and it will pop up ready for action, to close it -push down and twist the other direction.
