Sorry,

I didn't make myself clear. I don't want to remove the bulkhead shelf, but just the finished liner that sits on top of it. I don't seem to have the 2 screws that Tony suggested exist in the first aid compartment, but I suspect that beneath the liner I will either find the screws or else I will see a means to pull the first aid compartment out so that I can access the top of the fuel tank. This may be a trivial task, but my tendency will be to do the wrong thing and damage the liner or the interior trim to the car and regret it later....

Thanks.
