Thank you gents. This post caught my eye. I have read some member's experiences on the forum but decided to dig further in case I need to replace the twin pumps inside the tank of my '04 XJR.
So if I am correct, this is some of what I discovered:

Not all XJR cars have two pumps
The requirement for XJR pumps are more that of XJ8 cars with normally aspirated engines.
XJR pumps require up to 180L @ 4.0 bar and are speed controlled.
If you are handy, you can replace the motors inside the assembly without changing the entire assembly.
Some resourceful forum members have used BMW M5 pump motors in XJR cars.
Some original twin pump motors were Pierburg 7.22013.61.0 . This pump also crosses to the Pierburg 16146752369.

and https://www.ecstuning.com/b-pierburg...MaAoafEALw_wcB

1. Correct me if I am wrong about any of the above.
2. Please recommend other pumps that you trust to be from good manufacturers. Walbro pumps look good but they do not seem to offer XJR or M5 replacements . I do not care to use a no-name brand for $20. I mean , I would like to pay that but I fear noise and failure .
3. Did Jaguar use identical pumps in the "twin pump" XJR.?

 

did some more research. the earliest STRs and 350s use 2 fuel pumps from the lincoln aviator. 3c5u-9350ab. 270+ lph at 40psi. the m5 pump is supposedly rated for 140/72, the regular e39 pump is 130\50. a walbro 255 flows 180\70 the green top aviator pump units are interchangeable with and superceded by the pierburg ones so the car should be able to adapt


this person put the regular pumps in their car like 5 years ago.


@Lagonia

still using those $40 pumps? everything good?

 

this is what the green top setup looks like
