So, (see photos) the pump dropped right into the basket. Like it was made for it! Perhaps it was.
New (experimental) pump is the full cylinder design on the left in these photos.
Only difference I noticed was one being a full cylinder and the second hole on the TOP where that white plastic is. I don't know what that second hole in the top of the OE pump is...? Anyone?
The original pump is still good and on the bench. New pump is in the car. Trims are great (maybe better than before) and pump pressure is steady. Moves around a bit like it used ta, but steadier , or maybe that's just my imagination... but (from memory so pls correct me) is usually at and around 55.3psi. great! That's what I'm seeing. Again, not on acceleration or load...
One thing. Pump in the car at idle. I'm getting something that don't seem right. I honestly don't think it's the pump BUT my hands were so cold at this point that I packed it in. There is a subtle but absolutely present pulse or bump in the spinning or pumping of the pump. I honestly don't know if it was like that before... From what I understand (which ain't so much) the pulses from the fuel pump controller module in the boot is supposed to work in milliseconds. A speed of pulse that I should not be able to detect by feel or ear. So, maybe I put the sock on the spout at the intake on the pump on too tight? Maybe I made a mistake and the little flap plug stopper set up is being interfered with because of how the sock and pump are sitting in the basket? Maybe there is a small leak in the hose where it not clamped tight enough to the outlet spigot on the top of the pump? Or something. I just don't know and it will require a bit more investigation.
At this point, and I have not driven it or a lot of time has not elapsed, but I (in my gut) feel that the pump is a FIT... Time (just a little) will tell. This is that PIN hole I was talking about before whose action when the pump is running forces fuel into the bottom of the basket to keep it full.
Looks good. The perceived pulse; hopefully is not the difference in a PWM and Regular 12V. dc replacement pump. Hope the Land Rover had a returnless fuel system. Did a bit of looking and the 2006 LR 4.4L shows to be returnless. The earlier LR's could be a return type, but I am unable to confirm. Surprise, the Alibaba listing show this motor compatible up through 2009 in the Land Rover Discovery. Google will not answer a direct question and AI has no idea? Ha!

I wound drive the car and assess the performance at all rpm ‘s and at full acceleration in all gears before getting too wrapped up in the numbers you see.
the only benchmark that matters is the one when the rubber meets the road.
Jay, you are so close that I can taste the gas, lol. At the end of the day, this car, like all others, is nothing more than nuts and bolts, albeit with a wacky electrical system. As these cars continue to age, the availability of numerous components is either not available any longer or is dwindling. New old stock from suppliers is drying up by the day. So going forward we will be needing more solutions and or alternatives but trust me folks here will figure it out.
As far as cold weather Jay, remember no one has ever retired and moved north for a reason. Stay warm and thanks again
Jay, perhaps that is a Mould locater hole they use when produced. No apparent need as breather or vent. The repo has no need since mould was formed (copied) later. they saw no need for it. Thank you and keep us informed. It was up to 40F today. 60's next week.
On closer look last night (and one of my issues is being so rushy doing car work -or any- that I should have looked before installing the new pump) I think that that circle hole/spout is a dead end. Can't quite see down in there, but I agree. I think it's nothing,,, a leftover form molding and manufacturing process.
I kinda think the faint pulsing I feel and hear is a problem with the instillation of the pump, more than a problem or mismatch with the pump. We shall see. I need to take the car for a drive watching trims, misfires bad behavior, but that ain't going to be today. I hope it's the right thing and problem solved.
Hi Jay,
I'm all good and now retired, thanks.
I sympathise with the old house renovation:- if you're mid-point between elation and desperation then you are most likely on track!
Watching this thread with interest. Fingers crossed you guys are on to a winner here .

Do I really come across like a Sgt. Major??
Noooo, Like A Sgt MINOR, lol
CONGRATS on retiring. That's a big deal!
Honestly,,, I think it's the right pump so far. Now I want to know about the pressure relief valve on the top of the assembly...
I love working on the house. Just finished a sauna (big one) in the basement and now, next to it, a steam shower. Rehabbing a 1700steam generator that I got on eBay for 29$... Yup, 29$. Got it working today and I used an electronics forum to fix it, a construction and tile form to build the shower and a sauna forum to build the sauna! I love forums,,, if the culture is right...
I DO hate standing on the roof looking down on my cars collecting dust and DIRT and and and, being miskept...
Nah Michael. To me (and this is just me) you're life blood here and super helpful, civil and realistic. Humble. It's so so so welcome in the forum atmosphere. When on here it can be intimidating at first (and in general) and you're always super helpful and positive,,, well man I'll nevah forget ya...! Seriously.
I think I may be trying to be on here more, for what it's worth.

Not at all my friend. However, when you say something I do pay attention because you know what you're talking about even if your wife doesn't think so. lol
I don't drive much and on the few drives I've had,,, some street, some highway, one extended trip... Flawless drive. Pressures stay where they should and I think trims better than previous with this "alternative"... But here's the thing.
Couple days ago I got in the car, started it, rough running and psi at the rail according to the new (20$ rail pressure sensor was between 9 and 14psi with a p0191code... Spent the $130+ for the eurospare sensor, installed it. Same thing. I could hear the pump running full blast. Opened my little inspection port (access hole cut in the back dash) and had my wife key the car to ON, for the 2 second prime... Word of advise,,, don't have the coconut (head) in range of fuel stream when doing this task. If so, wear scuba gear, lol...
For some reason the clip with spring (I don't even know what it is) had POPPED OUT and full fuel stream was exiting the pump there, very little making it true the main exit to the rail. Only thing I could fish out of the tank with a magnet was the spring that you can just make out (maybe) in the photo. I'm imagining there is a ball bearing, and that cap you can see.
Yesterday (I'm sorry no photo) I removed the pump and jammed a small ball of aluminum foil and plowed in some JB Weld to fill the opening... WILL JB WELD HOLD, in your experience? I dunno. I was tempted to run a very small screw down in there but was afraid that I would obstruct the veins of the pump. I don't know where they are in the pump. Right on top?
Anyways, I'm headed to work and the JB Weld is curing. I will never have confidence that this is a fix. Looking for a solution. Open to any and all suggestions.
Don't know why that bit failed. A freak thing? I dunnO...
Sorry for the bad "mark up".... And the 2 circles. Only photo I have. The new pump is on the left. As you can see both pumps have this,,, spring loaded clip on top of the pump... I might just go back and order a second one now. So damn inexpensive... But maybe this failure is ONE of the indications of its build quality? I have no idea what to think.

Sorry to hear of your experience. I’m my early 20’s I swallowed some gasoline once, was never so sick, retched for a hour at least
i admit I haven’t read every post in this thread, but did you find a reasonably priced pump, or did you have to pony up major money for it. All I know about the 4:2 pumps is that they are very expensive compared to the 4.0 L pumps.

Hey Man. Good morning.
I did. Link below. this is the pump Im working on. Exact fit into the basket, as you can see (and research) from the associated numbers its in the family. RRover 4.2 engines. Besides this problem Im having the pump had been working flawlessly. Dont know what caused that little silver button to POP out of the pump. Its a pisser. I just ordered a second one. TARIFFS!? Came to 90$ this time as opposed to the $58 I paid the first time.

They are hitting everything, even preemptively before the start date.
I manufacture a frame brace for vintage Mustangs, and use domestic steel. All the USA steel companies have raised their prices to take advantage of the new rates for imported steel. The tariffs did not make USA steel a bargain. It still costs as much as the imports if not more.
the more things change, the more they stay the same.
(in French: "Plus ça change, plus c'est la même chose"), was first said by the French critic, journalist, and novelist Jean-Baptiste Alphonse Karr.
He published it in 1849 in his monthly journal, Les Guêpes ("The Wasps").
Solved????
