Hello Ladies & Gents,

I post this here, because I think it might be an "general" Topic, regarding all Land Rover Models. If this is the wrong sub-forum please move it to where it belongs. The story of this "repair" started a few month ago.

short history:
On our last holiday trip, last autumn, back from the Channel Islands, somewhere in France, suddenly the Lady (TD5, MY2002) won't accept any throttle and after a few seconds the engine went off.
Luckily we were able to roll aside of the road. I switched on ingition (from I to II i guess) a few times, so that there should be no air in the fuel system.
Fireing up the engine worked fine then. We could continue for another few kilometers then same behavior occured... I repeated the procedure and we were able to drive another few kilometers. And so on...
The intervals became shorter and shorter. We replaced the fuel filter, but unfortunetally this didn't change the situation a lot. We nevertheless had been able to continue our trip home that way, stopping every few kilometers, purging air, going on....
FYI: i changed Fuel Filter after the buy, and just a few thousend kilometers before this trip.

The next day starting the engine went fine, so i ticked off that topic, but....


After a few days of Defender-rest (no daily driver) I took the TD5 to work and on the way home, same behavior as mentioned above.

Facing the same issues again i decided something has to be done.

My amateur-mechanic anamnnesis: it had to be a problem regarding the fuel system. Electricity worked well, no errors on the ECU, fuel in tank, Engine fireing up but went off after a undfiniable time, no leaks (not more than usual ;) ).

I already heard of the "maintenance / access panel" for the fuel pump. My Defender had this already done to it, so it's been time to drill out some rivets. Opening the panel it seemed very clear what caused the behavior:
The fuel pump wasn't where it's supposed be. The fixing ring corruded, so the pump jumped out. This, on the other hand explained, why the problem only occured when the fuel tank was already on a lower level.

Another thing this situation sadly brings: theres dirt in the fuel tank.

My decission:
- Empty and clean the fuel tank
- clean the fuel pipes using compressed air
- Replace the fuel pump (overhaul the used one as spare)

What I've done so far:
- Removed the old fuel pump
- Emptied and cleaned the fuel tank
- cleaned the fuel pipes (compressed air). Therefore I removed the pipes at the fuel pressure regulator and blew air to the back, to be sure there are no bigger dirt paricles
- btw. I removed the whole rear floor, 'cause I wanted better access to some parts of the Webasto Therm Top (heater)


Now here's where I struggle with at the moment: There is this white plastic adapter ring that has to be fitted on the fuel tank. This ring has an inner and outer thread. When it's fitted correctly it holds the fuel pump and provides the "outer thread" for the black metal fixing ring that's holding the pump in place.
Using no mechanic tools it's only possible to turn the ring about 3/4 on the fuel tank. I don't want to use to much force and eventually destroy it...


So here's my question: Is there a special tool for this adapter replacement or, even better, a universal tool I just don't know the name of?
Or a special method to put it on? It seems to be a "one-turn-thread" / 360 degrees.

After opening the access panel in the rear floor:

After removing rear floor, but still the "old" white adapter ring visible:

New Adapter Ring so far, needs another quarter turn somwhow:

please forgive me any misspellings since I'm german ;)

and thank you very much in advance!

Folks,
I'm so happy. Today I spent a few minutes at my Landy, because I wanted to be able to move on refitting the fuel pump the next days.
My solution: I created my own "Adapter-Ring-Fitting-Tool" using two steel-angles and a few bolts:

That way I've been able to adjust the angles using the bolts. The angular corners allowed me to get some preassure on the white "knobs" on the adapter ring.
With very little afford the ring had been put in place.

I'm so glad this worked out, because a spend a lot of time the last days thinking how to go on here. Now the next days I'll be trying refitting the new fuel pump :)


If you're interested I'll keep youz up to date.
