I've been searching this forum for days trying to find the answer, but it doesn't appear to be in here. I've a 2005 XJR with a dying fuel pump - I assumed before removal it was the newer style that required the Pierburg 7.22013.61.0 pumps. However apart the actual pumps are from 2004, the part being 3cu5u-9350-ab.
After an afternoon of research I found the following: 1st gen Lincoln Aviator, 1999 - 2004 Mustang 4.6 GT and the SVT Focus.
Autozone pointed me to the Delphi CFE0443, it's not installed yet as the connection for the fuel doesn't have a flange at the top and afraid without it the fuel hose will slip off during use.
What has people used to replace the 3cu5u-9350-ab? Is the Aeromotive 11540 and option?
If your car has two pumps, then it is the older style and that is where the Pierburg 7.22013.61.0 pumps are needed. I have used these pumps as replacements in in my X350 SV8, built in September 2003, which has the same engine as the XJR. They work perfectly fine. My old pumps had the number 2R8U-9350 (Pierburg 7.28177.01).
If I remember correctly, Jaguar switched to a system with only one fuel pump for the supercharged engine sometime in 2005, but for the single pump system I do not have any part numbers.
I did actually also I order the Pierburg 7.22013.61.0, but these are very much bigger than the OEM ones that are in there. The car certainly has two pumps.

PM me. I have a set of good fuel pumps removed from a 04 XJR ready to be dropped in!

Hi Thomas,
Can you confirm that you have replaced both of your stock fuel pumps with the Pierburg 7.22013.61.0 units?
I have had a long running problem with the duel fuel pumps in my 2003 xjr but after lots of research and communication with an engineer at Peirburg my conclusion was that these units would not be compatible. If I recall correctly another forum member fitted these pumps as replacements and it didn't work for him.
The problem that some people had is that Pierburg made a lot of fuel pumps that look identical, but differ in the technical specs. For the supercharged Jag you need the pumps that were used in the E39 BMW M5, the pumpd used in the lesser models do not have the power required.
This is what my original pumps looked like. Mine is a 2003 xjr. I think these pumps are Ford parts. I ended up sourcing a good pair of used pumps and fitted them.
Symptoms are under heavy load and supercharger has just become audible power is killed and goes into reduced performance mode. I've also had reduced performance mode occour under light load driving around smoothly, even driving around a parking lot.

Ok, let's run through each:
P0171 - lean condition - bank 1. You have an air leak primarily on the passenger side of the motor. Two things come to mind. The booster hose that runs into the SC plenum. Known issue as the o ring hardens up and disintegrates. Very hard to remedy in situation.
The other offender for a P0171 could be the PCV valve that sits on top of the valve cover. As a starting point go from the air filter housing to the throttle body and make sure everything is connected and tight.
As a side bar - might be worth cleaning your MAF with appropraite cleaner. Let dry completely before reconnecting.
P0300 - Multiple misfires detected and...
P0316 - misfires exceeds value by ECU - both of these ignition related codes would definitely be a power killer under load.
Disregard the P1000 - means your emissions are not set yet.
You need to dig into why your getting all those misfires and you want to remedy quickly as that unburnt fuel will find its way to the cats and destroy them.

Codes are pointing at ignition related issues...
Look into your coils and spark plugs...
Forgot to say, spark plugs have been replaced and the fuel pressure is only about 50 psi
With these cars you do not want to go down multiple paths. You'll get even more frustrated.
The power train codes presented are pointing to an ignition related issue... I'd get that sorted first.
Multiple misfires, excessive misfires will negatively affect power and performance for sure.
Since your plugs are new (did you use OEM NGK plugs or another brand?) Check each connection on the coils to ensure a tight connection.
Fuel pressure is ok.
Now, your Fuel Pressure Sensor might be problematic... maybe... but the ECM would throw a code, but I'd focus on rectifying the multiple ignition misfire codes first. Again - dead ringer as to a loss of power under load.
PS - if you used any other plugs other than NGK OEM spec I'd get that sorted, quickly!
