Thread: NOT theWastegate Actuator operation - the fuel pump!

Fuel pump arrived today, and vroom vroom! 5km test run and all good. Will do something more substantial tomorrow. Thanks all!

To sum up what I found re LR vs aftermarket pumps, seems to be two lines of thought.
1 they fail often enough so your best off buying the real deal
2 they fail often enough so you might as well go for a cheap aftermarket pump

Both lines of thought recommend carrying a spare if you're going remote.

Personally, I'm going to try and gut the dud pump and turn it into simply a pickup hose and sender unit, and attach an external HP Bosch pump if the new one fails. At least it won't be so much mucking around next time!

Happy Roving, all.

G'day all,
One thing to remember is to allways (where practical), keep the fuel tank at least 1/4 full, to keep the pump cool and lubricated these pumps are quite tricky inside,they comprise a low pressure ,ceramic disc pump to pump fuel out of the tank, to the filter and back to the pump. Then , a pair of metal gears pressurise the fuel up to the engine via the regulator ,so they like to be surrounded by fuel.

I killed my first pump in a few months of owning the TD5 by running the fuel down to the light came on,as I did in the D1.
No more,and buy genuine in my opinion, (I have a non- genuine I take as spare on trips) especially fuel filters....,but thats another story. Glad you got it sorted,
Cheers Gregg

Are you sure your pump wasn't cactus anyway? How many KM/years had your D2 done when it failed.

If the pump had a design fault which resulted in rapid failure if run below the 10% remaining warning light this would have been an issue from new.

Indeed the illustrious Pedro The Swift posted this in another thread

The pump itself sits in a little bucket of its own fuel, about a saucepan full. this remains even if you run the car out of fuel---

Myth Busted, as they say.

Hi Paul, the car ,and pump? had 50k on it when I bought it ,so was practically brand new.The depression in the tank is only about 20mm deep, no-where near enough to cool the pump, but more importantly,the ceramic discs do not like running dry,and if your moving,it doesn'ttake much to get air in the pick up. The same goes for pumps in Commodores and other petrol cars, when we had high fuel prices a few years ago, RACQ reported many" in-tank" pump failures due to people running their tanks dry?
I'm not saying you will kill a pump if you do run low on fuel, but mine is now 5yrs on and another70k ,and I fill up at about 14 . I did run it bone dry every time initailly , till I could hear the pump cavitating!!!
Anyway, food for thought!!
Cheers Gregg

I know this is a bit of an old thread but I have replaced my pump twice now, first with a 2nd hand one cause thats all I could get where I was and the next was a new LR jobby. Bothy times the symptons were the same, still had 1/4 tank, no light on and car ran out of fuel!! it was parked leaning to the left a fair bit. What happened was the fuel ran to the side of the tank, now this should not have been an issue as the swirl pot at the bottom of the tank would of had enough fuel to start and run as it recirculates through it until you move, get level and going. However, what I discovered on the last pump was the swirl pot actually leaked the fuel out around the bottom and gave the effect of being out of fuel. I pushed the car to level ground, did a out of fuel restart and away it went. As long as it was level it would always start, even when the fuel light came on (deliberate test). The new LR pump will still leak out from the swirl pot so no fuel to start on a slope. I now make sure when it gets down about 1/4 i always park level and have had no problems since. I didn't bother with a parts warranty claim because the local LR people had no clue what I was talking about, so now just park level when it is 1/4 left.
Hope this helps anyone else experiencing the same problem/s.

Just gotta love the quirkiness of Landrovers!!
