High pitched squeal !

High pitched squeal !
My 1993 XJ6 has developed a high pitched squeal coming from the rear of the vehicle. Squeal present when stationary and driving, louder when you open the trunk lid. Fuel pump about to give up the ghost? Any thoughts on this? If it is the fuel pump, can it be replaced without removing the gas tank? Any help would be greatly appreciated.
Many Thanks,

I can't think of anything back there that could cause that noise when stationary except perhaps the fuel pump .. if it is indeed the pump, parts are quite inexpensive but unfortunately the tank does have to come out.

It isn't that complex a job, but a bit labour intensive.
If you have to do it, lots of advice here on the forum.

Thanks Larry,
You're a gent make no mistake! Not looking forward to this but I'll give it a go. I've never known of a fuel pump making this sort of noise, usually they just fail. I've changed out several fuel pumps on other cars I've owned. This squeal is very similar to that of a dry motor bearing.
Appreciate Your Input,

Hi Al,
I think you and Larry are right about your fuel pump, but there are three other possibilities worth investigating just in case. The radio antenna motor is in the right rear fender behind the carpeted trim, if you have a CD changer it will be mounted somewhere in your trunk, and if you have the rear Self-Leveling Suspension it could be possible one of the shock absorbers is leaking pressure (I know, a remote possibility).
Before you pull your fuel tank, use a long screwdriver or socket extension as a stethoscope; touch one end to the fuel filler opening and the other end to your ear. This should tell you if the squeal is definitely coming from the tank. On your '93 the fuel filler neck is welded to the tank so any sound from the tank will be just as audible at the filler opening.
Please keep us informed.
Cheers,
Don
