Fuel Tank Repair

OK Folks, from other threads on this forum, I gathered all the info and tried to mend the fuel leak problem on my 89 Civic. Was able to remove the bottom back bench seat (holy crap Honda did a good job of first, hiding the bolt, and second, worst location where one would need a twister wrench). The only thing of interest was a circular (about 5 inch diameter) metal cover with 3 small bolts.
QUESTION: Is this the 3P connector mentioned in the Honda repair manual.
When I unscrewed the 3 bolts and removed the metal cover, I saw an electric connector with some metal part sitting inside.
QUESTION: Is this the Sending Unit, and is the connector the fuel guage wire.
QUESTION: Once I disconnect the 3 bolts, and undo the fuel hose protector, and the two way valve cover, (and disconnect the hoses), will I be able to drop down the fuel tank (assuming that I will properly remove the two clamps that hold the tank) ?????
Ny concern is, once I drop the tank down, will the sending unit and fuel pump be still connected to the tank??? More so, Is the fuel pump and sending unit, integral part of the fuel tank ??? I am worried that once I drop down the fuel tank, I may disconnect something at the top, that might have connection to either the sending unit or the fuel pump.

If you are dropping the tank I would disconnect everything, or you can pull the sending unit out of the tank.

If you didn't know... They have a gas tank sealer you can fix a small leak without draining the tank. You just apply it to the outside. It looks like a stick of moldable JB weld. If you can see the leak that is.

Thanks smoghog, but it still does not answer my question.
I know the connections at the bottom of the tank, but are there any connections at the top, which I cannot see, especailly the sending unit and the fuel pump. How is the sending unit and fuel pump integrated with the fuel tank, is really what I want to know. The fuel pump sitting at the top part of the tank, must connect to somewhere else, which is the connector I am worried about, that I might disconnect when I drop the tank. The same thing goes for the sending unit also - How is the sending unit sitting on the fuel tank??
I may or may not try the JB weld. May change to new fuel tank. If I change the fuel tank, is it easy to move the sending unit and the fuel pump to the new tank?????

You have allready removed the back seat so you saw the three bolts and the connector. I am not sure but the conn should be the power to the fuelpump and the sending unit. From the book. There is one connector on top. So there you go. the other connections are hoses at the bottom corner which you know about.

And the sending unit is "in" the tank along with the fuelpump

Thanks.
I have a bigger problem now. Phoned gazillion shops, including Honda dealerships, and the sending unit for 89 civic is discontinued and not available anywhere. Any ideas.

One or two, Find an electrical shop to rebuild it. Junkyards,maybe.

Are you sure it is bad. have you checked it out yet?
Might just be the float?
