I just had to replace the Fuel pump assembly in my 4.4L 06 HSE this weekend after the pump died in Maine on Monday. My pump open circuited, verified all the way down to the terminals on the actual pump motor, so the rest of the unit is fine. I see no reason to just trash an 800 dollar fuel pump assembly if I can find an equivalent fuel pump (the actual little 1 1/4" pump in the pump assembly) to put inside it. Has anyone found a suitable replacement that puts out 65 psi that can just be swapped into the housing? Don't know what the required flow rate would be, wild guess would be around 300 Lph. The ones in the BMW pumps only put out about 50 psi so I cant use one of those.

Do you have the part number (Bosch?)?
You might try contacting Quantum Fuel Systems to see if they have a replacement. They had a pump for my 2000 P38. They only list a pump for the 2006 LR3 and Sport but then they don't show anything for P38 so who knows.

You have little different fuel system on 4.4. We dont have on 4.2 fuel return pipe but you have. And the pump is little different said by a russian mechanic. But still I didn’t saw a 4.4 fuel pump.

You can try a pierburg high performance pumps. The oem one must be a vdo.
You have to bypass electrical connector and everything will be ok.

My friend install this one

I think in an old post of mine, I did this swap with info included. Turn your phone off and have a fire extinguisher on hand just in case. Mine tank was nearly full when I had to get my hands in there.

Thats probably the same pump, the LR3 and the sport have the same engine, just all the other plastic parts and level sensors are different.

My tank had about 25 gallons of in it when I started at about 35 degrees F. I had two 5 gallon lawn mower gas cans, and I went out and bought one of those roll around 14 gallon ones with a filler nozzle on it (for filling boats, snow mobiles etc) and I have a little battery powered harbor freight barrel pump, so I pumped the tank down completel empty on the left side where the main pump lives, and dropped the right side where the jet pump lives down to about 4" because the jet pump is easy to dislodge from its mounting sockets while the main pump is a bear to get loose. Took about 2.5 hrs to drain replace and refill, put the rug back down and generally reinstall all the trim, cover panels and load all the junk I leave in the truck back in. Now I've got this perfectly good RR fuel pump assembly with the level sensors and everything just sitting for the want of a 50 to 100 dollar pump module.

Eerks me to have to toss the whole thing away, those level sensor cost over $100 each from LR. I know theres a pump out there that will just slide back into place and work fine. I'm going to disassemble the plastic barrel part that the pump sits in tonight and see if I can get the pump out of the hole it in without snapping something off.

Which fuel pump you bought?
Exact fit or you have to add some wild west connectors

I bought the VDO brand pump, and a new filter/tank cover. The only physical difference between it and a LR version is that it does not use the short connector harness between the pump and the fuel filter, the pump (and level sensor) wire connector plug directly into the fuel filter (which it the right tank cover on the 06-09's). A LR harness has a short (4-5 inch) harness that adapts the internal tank harness (which has a larger connector) to the filter feedthru connector which is smaller. Don't know why they do that, because the last time i had an issue with my pump it was one of those connectors that caused it.

VDO used to make good electrical products, so we will see it I made a good choice and it lasts a long time , or if I should have stuck with the LR version, although I have now replaced two LR pumps in my truck.

Here what the fuel pump looks like when you get it out of the bowl in the right side of the tank.
283845

It's kind of an odd setup. The pump apparently has a low pressure outlet on the bottom where the white plastic piece attaches. That low pressure outlet feeds an eductor that pushes fuel out the larger tube on the left side of the picture. I think this setup allows for just about every drop of fuel thats available in the tank can get used.

283846


The fuel comes in the swirl pot under that white plastic part on the bottom where the black gasket is. That sits over a hole and passage attaches to the fuel filter on the outside of the swirl pot. Fuel that comes out the large white tube circulates around inside the swirl pot and enters the pump through that gold bag on the right and goes thru the plastic passage at the base of the pump and is discharged out the top two hose barb connections. The small one feeds the jet pump (eductor) on the left side of the tank, and the larger one feeds the fuel filter bowl assembly in the right side access cover.

I think I have found a direct replacement, it comes from an 06-2014 Volkswagon CC.they put out 4 Bar at 120-130LPH and I think they dead head at 80 PSI, hard to get exact specs for the VW pump. They run between $20 and $30 each. I'm going to order one and see if it is a direct fit or not.
