Ok guys and Girls.
Looks like its time for me to replace my fuel pump (oh what joy awaits me )

The reason.
Car runs great no hesitation or stalling but if the gas tank is less than a 1/4 full she will not start (or starts and dies after the fuel in the rail runs out)

I did the engineer test and my tank level reads fp1, 114 fp2, 48 so looks to me like my transfer pump is the culprit.

Now knowing that my main pump is probably not far behind and I dont want to have to drop the tank twice I am going to change them both.

now the reason for my post.

Does anyone know the part number for both Electric pump motors.
as the rest of the assembly should be fine I just want to change the motors out.
I have done some hunting around but can only find the complete Fuel Pump assemblies.
Looks like she is true to form with 115K on her.

 

Paul: I also thought our X-Types had two fuel pumps: a main pump to feed the fuel rail, and a 2nd pump to transfer fuel over the hump. But astromorg shows us there's only one pump, per the diagram in post #5 of this thread: https://www.jaguarforums.com/forum/x...ailure-131137/

XTypeparts.com has a picture of the single fuel pump with the suction that pulls gas from the far side of the hump:

Note there are two fuel level sensors, but only one fuel pump.

Welsh Enterprises sells just the fuel pump for $85, which is working well in my 2002 X-Type for the past ~10K miles and counting. They show part # C2S41300 for the pump only:
Welsh Enterprises, Inc - Jaguar X-Type Fuel/Emissions Fuel Tank, Fuel Delivery & Return Parts - Fuel Pump - X-Type

The entire pump + canister assembly is part # C2S35274, typically sold for $300+.
