Thread: Low Pressure Fuel Pump replacement options

I'm probably about to do the pump replacement, will let you know if/how it goes. What are your symptoms?

Fault Code of P2290-00 (2F) injector pressure too low. (thanks mister 11D BT code reader!)

Was going into limp mode after acceleration and with transmission F(could repeat every time).

Tested with a low pressure guage at the schrader valve in engine bay and was only reading 3psi on idle (should be around 7psi) and dropped back to 1psi at 2000rpm. Couldn't supply enough fuel to the HPFP at revs. Still hoping it was a faulty fuel filter at this stage as i'd already fitted a new fuel filter.

Then tested current after bridging where the 40A relay is, and the LPFP only pulled 1.9A (healthy LPFP at 4Amp draw).
Have removed tank and disconnected the LPFP. Gauze filter was pretty gunked up.

Just looking at all the $ options re replacement at this stage.

Thanks Peter, how hard was it to get the tank out, and then the pump? Did you have a hoist, or just do it on stands?

I put it into Off Road height, blocked wheels and used a trolley jack on drivers rear to give a bit more height, then used jack stands to support chassis.

I had removed long range tank for another issue, so not sure if you need to drop spare tyre to get access to remove filler pipe. I don't think you'll need to.

The fuel line clips behind fuel filter ( which you'll need to remove) were a bit fiddlesome to undo.
Remove side silver heat shield on tank. Unclip brake cable etc on top side inboard of tank.
Undo large filler pipe at back of tank.
Used a trolley jack to support tank and undid the 6 bolts that hold tank up.
Unclip side fuel lines and lower tank down enough so that you can see into the pump module access cover. This took me a while as mine was filled with clay/mud from many an adventure I've had!
You'll need this to be clean as possible, as the large pipe is removed by squeezing the sides in, much like you would a child proof metho/turps bottle. This took a bit to see initially as it was covered with dried mud. I even had to resort to putting on my glasses! The small pipes have a side pushin release like the ones behind the fuel filter.
Disconnect the wiring plug. This sounds easy, but as mine was caked with mud, I had to squirt bountifull amounts of CRC into little plastic release to clear the grit and allow the clip to be depressed.
Tank dropped out easily and was easy enough to manhandle. Just lifted it on a wheelbarrow for ease of working.
To remove internals, I'd recommend a Haynes workshop manual or maybe see if you can find a online tutorial, as whilst it's not hard, there is no way I would have as a first timer been able to nut out what was what, and the disconnect sequence.

Electrical pump is a Walbro GSS 503 04. Will know in a couple of days if I have had any luck in sourcing a Walbro genuine pump replacement instead of the " all completed LR genuine $950 one". Would be a lot easier to install complete LR one, but i'am prepared for a little pain to save $800.

This is a reasonable DIY task, but I' am lucky to have blessed with the gift of dumb persistence!

Hope this helps.

Cheers

In this thread ( DISCO3.CO.UK - View topic - TDV6 In-Tank fuel pump.... ), they mention two options:

1) Dismantle your pump housing; clean your screen/fuel pickup; install a low cost Peugeot pump - | Car PartsRetailer

or

2) Buy complete replacement LPFP housing - LR014998 TDV6 IN TANK FUEL PUMP MODULE OEM VDO MODELS WITH 2010 FUEL TANK MODIFICATION

Good luck!

Cheers,

Unfortunately there was a revision on the advice of after market pumps at DISCO3.CO.UK - View topic - Acceleration Fault So still unsure what/if any aftermarket single pump motor will stand the test of time.

Also the one at AdvancedFactors is for a 2010 tank, mine was born 3 years earlier. Is different looking to mine. Anyone fitted this one to a 2008?

Am still waiting on my contact to confirm whether he can source a genuine Walbro pump. If not, i am not prepared to take the chance on a dodgy part and will just have to man up and buy the LR complete pump.

Sorry to drag up an old thread, how did this end up? Did it require a full new pump from LR or was there an alternative.

I currently have an intermittent fault P0087 - low fuel rail pressure. Sometimes it will be OK for several weeks other times it will throw a wobbly 30 times in 100kms.

The suggestions have been that it could be the HPFP or the LPFP. I checked the draw of the LPFP at the fuse and it is at 3.45A which seems as though it is possibly a little low and possibly should be up around 7-8A or even more, so I am leaning towards replacing it (first).

Daniel.

Hi Daniel, had the exact same thing happen to my vehicle after just about replacing everything it turned out to be the HPFP . Now that it has been replaced the car really runs nice now. Seems to have more power and has better fuel economy
