Just to let you know that the 300 TDi Discovery has a "Sedimenter Bowl" which is a pre-filter, underneath the car near the rear axle. Most people in the UK are not aware of this as garage forecourt pumps usually have built-in filters. In fact some UK LR enthusiasts remove the unit and say that it is just a waste of time and space. On the other hand the pre-filter is very handy in places where jerry-cans are the norm. If one examines the pre-filter one will often find what looks like an egg yolk in the bowl so one may wonder how much the egg yolk installers get paid by the factory! In actual fact the "yolk" is usually a glob of bio-degraded diesel caused by condensation or damp in the fuel. It is of course highly desirable to trap the glob before it reaches the paper element filter.

One thing that might be worth carrying on a long trip is a spare lift pump as these sometimes give lots of trouble. I had a bad experience with these which in the end turned out to be fourth pump lucky! The problem was very poor running and the kangaroo effect so a new lift pump was bought (it was an aftermarket cheap brand with a dreadful reputation but at the time I didn't know that) The original Delphi pump would blow but not suck so I assumed that the new pump would fix things. A short road test showed that the car was still limping so what could it be? Next I took the injectors to a diesel fitters but the pop pressures were all about 2400 psi and the spray patterns were excellent so it wasn't that. By now I was thinking cracked head or blown head gasket which was making me feel quite ill. Nothing could now be done until new copper washers for the injectors arrived. Once they came I was able to do a compression test using a dummy glow plug adapter. Although the compression figures were not Rolls-Royce after a few turns of the engine the gauge was showing about 400 psi which to quote an old saying "is good enough for government work!" I was so happy that a new head or head gasket were not required that I ordered yet another lift pump. Unfortunately when it arrived there were no union nuts or olives and once again it was that infamous brand so I didn't even bother with it. Next a new Delphi pump was ordered and when the box was opened the superior quality was quite apparent but you get what you pay for. The new pump was fitted and when the engine was started it was immediately noticed that it now had a smoother and steadier even beat. On the road the vehicle was back on top form with white-van-man performance available! I checked the first replacement pump to try to discover what was wrong with it and came to the conclusion that the olives were the fault. They were very hard brass and they would not crimp down onto the pipes properly so if you are going to take a spare pump, take a Delphi! Good luck!
