Thread: Flat Bed Truck

When the replacement turbo produced an oil leak a few weeks ago, LR tightened a bracket or clamp on it and also tightened the fuel filter, as there was a slight fuel leak too.

Move on two weeks or so and diesel was hosing out!!!

I should have put a bit more into the previous post.



Some larger common rail diesel setups have 3 pumps in them

1. The lift pump this provides a constant low pressure high flow of diesel usually there is a dewatering filter with a water sensor on it in this system pressures are typically in the order of 4-8psi. Its primary responsability is to ensure that the next pump doesnt cavitate and is fed clean fuel.

2. The next pump is the pressure pump its purpose is to ensure that the injection pump is always primed and supplied at a constant pressure while being fed the ultra clean fuel that common rail injection pumps require.

3. The last pump is the injection pump this is the one that lifts fuel pressure from "that'd make a good flame thrower" levels up to the "that'll cut steel" arena.

Smaller engines dont need to meet the wildly varying demands in terms of fuel flow (theres very little difference in fuel consumption for a 400HP turbo diesel making 50HP compared to a 200HP turbo diesel making 50 HP but massive differences at the 400HP level) and cooling and so can simplify the system, typically this involves removing one complete element of the pumping setup.

The ford version of common rail (up to 2010 edition stuff) had the lift pump pulling double duty (so a relatively low pressure going into the IP) which means you can use relatively cheap filters as they dont deal with all that much pressure (typically <20psi)

The merc version has the pressure pump pulling double duty (higher pressure going into the IP) so run a heavier duty filter but as they dont usually have a self priming capability they typically run an electric pump in the tank and run a higher supply pressure (20+psi)


I was under the impression that the D3/4 setup was similar to the Merc system.

The D3/4 just has a low pressure pump and then the HP pump - the main issue is that Landrover placed the filter above a cross member where piggy fingers have problems getting it in and as such is easy to stuff up - I had a couple of goes to get it to seal last change.

The filter should have been placed about 2" forward with a removable protective cover and all would have been simple.

So you know what ****s most about this....?

Yup it could have been designed a bit better...but in my experience Euro Planes, Helos and Cars are not designed with maintenance in mind......in most cases....LOL!!!

But it comes down to an issue of maybe Mr Fumble Fingers....and I've got fuel all over my driveway and my street...

But wait, it's not that....it's the fact that my D4 ends up on the back of a flat bed....everybody sees that. It's not an ego or arrogance thing, but once again LR get this continuation of an unreliable car tag.... over something so simple.

That ****s me....LOL!!!

Hey Celtoid.... You forgot to add Metros and MU2 to your list

We had the same issue of a leaking fuel filter following a dealer service on our D4, to cut a long story short after the car was returned to the same dealer for inspection and repair. It leaked again and this time it was suggested to my wife that I was tampering with the filter!!!
What followed next was a formal letter of complaint to LRA regarding the incident, the accusation and the attitude of the very clever service manager. While LRA followed up with several phone calls no contact was ever forthcoming from the dealer.
We received a letter from the dealer recently saying that the car was due for its next service, not a chance. Our service costs now will include a 900k return trip to our next closest dealer.

X2.........EXACTLY

Never had an LR let me down ever,maybe i have been lucky.Oh,that is not counting a stuffed battery at 5yrs old in the D2.

Today my D4 comes up with the' can't find the smart key again',& this time won't start.It did it once while i was out west on the farm a few months ago while the engine was running,but hasn't done it since. After a lot of frigging around eventually it does start,then it does it again later in the day.Eventually it starts ,so take it home,suppose it has to go to the stealersHopefully it won't start Monday,so they can pick the friggin thing up themselves.Yer i know it will go on a tilt tray,but i haven't got time to take it to the stealers.

What is it with this key,why not have just a normal one,can't see the advantage of this smart key crap.

Mine's in danger of ending up on a truck due to a rapidly degrading compressor, having dropped to the bump-stops whilst trying to get some extra height to get home.
