I've just had my fuel pump changed at 171,000 miles (it's the second replacement the car has had). It was noted that the connector block on the evaporative loss flange (NNA5954AA, Fuel Tank-3.2/4.0 Litre-Normally Aspirated-Unleaded-Not Usa - Parts For XJ Series from (V)720125 to (V)812255 (X300) | Jaguar Heritage Parts UK) which delivers the current to the fuel pump is a bit knackered.

Anyone got anything spare, or know of where you can get that flange?

At least I should be able to swap it without taking the damned tank out again.
