Question HELP, Fuel Gauge is.. ill at ease! (technicals inside)

Note:
(I posted on bimmerforums a week ago, no replies. I think they deal mostly with cars)

Anyways,
I have a 2001 BMW x5 3.0 standard, 60,000miles.


The fuel gauge is acting up:
-It moves when you turn on the key.
-Its been reading about ¼ tank.
-It was working normal the other day... Now it's back to 1/4th.



After some Google searching I found this.

Incorrect Fuel Gauge Reading:
Model:
BMW E53 (X5) vehicles produced before August 17 th 2000.
Complaint:
After the tank has been filled the fuel gauge will not read “full”.......

......These errors are caused by a non-conducting deposit being formed on the conductor surface of the fuel level sensor...
(Then something about resetting a memory) –is this important?

If this is the problem,

I would like to take a shot at cleaning up the "non-conducting deposit" (corrosion?) on the contacts of the sending unit before resorting to the repair shop.
Can somebody explain how to get to this thing?


So far:
-I do not know the shape or exact location of the fuel tank (I can’t find Google pictures)
-I popped off the right side of the cargo bay + a cushion between the seat and door
-I can only see a small part of the tank. (No connections visible)



-I do not want to spend hours popping off random panels.
-I am open to all suggestions or help anybody is willing to give.


Thanks
-Wes
