patrol people...
i have a 2000 4.2 turbo diesel, 110,000ks recently pulling a 17 ft caravan. truck would not exceed 2000 rpm. regardless of how far the pedal was pushed. suspected a fuel problem. drained fuel filter and added injector cleaner to no avail.
told by son in law to check filter in injector pump.. a small brass gauze filter about 3 cm inside the injector pump. remove the inlet pipe 17mm bolt then use a screw driver (or i found a cotton bub ideal) to lift out the filter. filter is about 1cm long and .4 cm wide . washed out with thinners and then compressed air . there is also a coil spring to remove before the filter. car runs terrific 3400rpm without a miss...
my workshop manual (nissan) gu, but same inline pump does not show any filter.
told this is a common fault in the bush ,where the farmers forget to change the fuel filters.. change mine every 40,000 now going to 20,000.
hope it might help someone

Yes, it appears there is a fair bit of crap in some fuel storage tanks. A good mate who does his fuel filter every 30,000 recently found his fuel filter to be so badly clogged with muck that the car would hardly overtake on a flat road with no load.

Recently discovered that fuel bowsers do not have filters as standard !!!

HMMMPH.

the reason behind fuel bowsers not having filters would be because the 15 year old that works behind the counter wouldnt have a clue how to change the bowser filters 185621836453 times a day.so its left to the end user.
cheers

Met a poor bugger who came across the Barkley and thought he'd done his turbo in .He was a happy camper when I showed him the simple solution. Wanted to shout me a carton of beer he was that impressed.

I'm a little confused (I know - nothing unusual about that LOL)

Is the brass gauze filter before the main fuel filter? I thought fuel would have to pass through the main cartridge filter before getting to the gauze filter at the injector pump. So how does it get crud in it??

The gause filter is after the main filterand is to stop any lint etc from the filters.Euro trucks have them everywhere.

OK thanks. So the gauze filter getting blocked has nothing to do with dirty fuel then, more to do with poor quality main filters.

"more to do with poor quality main filters."thats one way of looking at it or other is added protection of the injectors.lol
Now you know the solution it doesn't really matter does it.
