I want to disconnect the fuel hose from the fuel "rail assembly" at the left side of the motor. There appears to be a quick-disconnect/connect fitting that is safety-guarded by a simple black metal bracket. The fitting looks similar to that of GM products. I tried to disconnect. The car had been sitting for several weeks, so I assumed there was no fuel pressure in the line forcing the connection tighter. I have the little GM plastic tool for this, but it doesn't fit and is useless. Additionally, the connection seemed really tight and could not rotate the connection.
Question: is there a special Jag tool required; and if so, what is the part number/cost/etc. Alternatively, am I just missing something in the procedure.
Thanks

 

Fuel line Spring Lock Couplings:

Is this the type of coupling you need to release?

Graham, it is the coupling. Many thanks.

Rey,

Pleased to hear it's the right one. It certainly looks an unnecessarily complicated coupling but must make for a quick assembly job in the factory.

I have a bit of self interest in getting to know the XK/XKR as it will probably be my next Jaguar model.

This also answers my question with my 05 XJ8.
