There is a panel there, but it'* not above that unit in a way that would permit removal of the sending unit/pump. I'd have to check to see if it would allow enough access to repair a leak or not. Or you could. I'd rather not un-seal my access panel without a good reason.
You may be able to lower the tank just enough to repair something on the outside, but in the long run, you should check your fuel pressure. Your car is old enough that your pump may be weak, so you can combine this work with a pump replacement.
