Toyota Repair: 1987 TOYOTA CAMARY, rubber gasket, filler tube

Question
I HAVE A GAS LEAK AT THE REAR OF THE CAR. IS THE FUEL PUMP LOCATED AT THE REAR BY THE TANK? COULD IT BE THE TANK LEAKING? HOW DO YOU GET TO THE GAS TANK? WOULD THERE BE A LINE LEAKING FROM THE TANK?

THANK YOU

Answer
I believe the fuel pump is located inside the tank there is a cover with some 8mm bolts that is mounted on top of the gas tank, the fuel pump and the pickup screen and the pickup tube and screen are inside there is a rubber gasket that may be leaking, not sure what could be leaking, on a car this old it could be many things, I don't have a lot of information on Toyotas before 1990 and it's been a while since I have seen a 1987 with a fuel leak at the rear so I can't use any previous experience with this, there could also be a leak at the filler tube or the fuel sender gauge plate on top of the tank,there is also a rubber gasket under the plate, you need to drop down the gas tank to remove these covers.
