Sory to hijack a forum but I’m in the same position as the OP. Have acquired an 1997 x308 and need to remove the fuel sender to siphon fuel out.
How did you remove the fuel sender? I have a brass ring holding the plastic sender in place that needs to be turned in order to get the sender out. Is there a special tool I’m missing?

Hi MJSS,
You may save yourself some time and trouble by using the procedure described in post #7.
Cheers,
Don

I had this problem with my 1999 XJR. I bought online a simple plastic tube pump device that I could push into the filler hole and hand pump every last drop of fuel that was about 9 months old- about half a full tank, into several small containers. I have now filled it with 98 octane and some Redex fuel improver. Unfortunately i drove the car for about 15 miles, so we are investigating new plugs and a new catalytic converter-it still had the original one after 128k miles!

What were the symptoms that caused you to suspect a catalytic converter requires replacement?

I took it to a local Jaguar trained specialist who checked the engine was OK, and the fresh fuel is working, but performance is very lumpy, and although they did a brief test, and suggested new spark plugs, first remedy, as they are likely to have been, contaminated. They feel they need to get it up on a ramp and do tests to check the catalytic converter, as stale fuel could have contaminated the fume extraction of the Cat C.. Its not certain, but a four hour check rather than half an hour on the computer /4 full as usual. Been using my wonderful Tesla , (until the main battery failed-replaced under 8 year warranty!), so XJR standing still with battery disconnected.might sort out the problem! Do you think this is unlikely?The old fuel was quite brown in colour. eight months ago petrol prices were low so I filled her 3/4 full, not 1/4 as usual with a visit to the local garage first stop on a trip..

Recently, I have seen cars that would shut down due to catalytic restriction. Who knows what
they are adding to the gasoline before it reaches the pump which could ultimately contaminate
the cats. In most cases though, you would get a code that indicated the cats were not operating
efficiently, which gives you some indication of trouble.

The Cat's can work perfectly up to 300K, but their sensors are like spark plugs and will go out long before the catalysts do, there's 2 cats, one for each bank. Not sure if your car's engine is AJ26 which have 2 x O2 sensors, or an AJ27 engine which has 4, pre and post cat - my money is on the sensors, not the cats. 15 miles isn't even enough time to get the car up to temp in some cases.
