    Removing my tank on a 1994 XJ6 with in tank type pump, my Haynes tells me you have to remove the two fuel lines from under the car but i dont have axle stands, is there an other way to get at them?

    Well my 94' came loose as per the book. The book takes apart a earlier model car so procedures are different, sometimes. Try using spare tires from your Jag and your wife's then something else very safe.I had a 60' T-Bird lite on my hand in 1990 and belive hurts. Just use sturdy things that won't move if the car does slip. Don't EVER rely on the jack EVER! Let the weight down on the wheels. Just thinkin....Go buy some jacks.

    How do you remove the fuel tank from a 1992 XJ6 Jaguar?

    Hi, you have to Jack up the car, and reach above the rear end , remove the 2 clips holding the fuel lines and give them a slight twist and pull. This will remove the hoses. Then you will have to remove the hoses and straps and wiring in the trunk, in order to remove the tank.

    1993 jaguar xj6, do I need to drain fuel out before removing the fuel lines?

    If the tank has much over a gallon (5L) then you would be best to drain the remainder of the fuel, otherwise you should be able to change the lines without looseing much fuel.
    The obvious thing to note, is you are working on a fuel system, and the risk of produceing a fire is very high, even with the tank empty!

    Where is the fuel filter on a 1993 xjs 4.0 cabrio?

    think its underneath by the fuel tank ,but you shouldnt need to change it i have a 94 XJ6 4lt and i have never had to touch anything ,just changed the oil and filter ,evan the plugs havent needed changing in 2 yrs ,but you must polish it every week and clean the leather once a month with that stuff that keeps it supple .and dont forget to polish the chrome exhaust cover on the exhaust manifold

    1993 jaguar j6 soverign

    93 Jaguar XJ6, sadly the pump is located in the gas tank and the tank has to be removed from the trunk to gain access
    Pretty basic replacement except above the rear axle underneath the car are where the fuel lines are connected, they are quick connects and are help in place with a spring pin, do not remove the spring pins, you just turn the pins to one side and the hoses will pull off, but you will need a rack to do this, It is impossible to get to the hoses with the car on the ground.
    The tank itself is self is pretty easy, just be careful when you remove the screws holding the fuel filler gater assy as you can tear the rubber and they are expensive to replace.
    Hope this helps
