I am now facing the same situation and have this same question. How do you get to the fuel lines under the fuel tank to disconnect them? It appears that one has to drop the entire rear end assy down in order to get to them. Shurly not even Jaguar would be that stupid. What special tool will I need to get them disconnected and where can it be obtained? Thanks
