There is an access cover under the back seat. Remove the back seat by removing 2 bolts at the front bottom edge then lift up the front of the seat and pull it out. Then the seat back can be removed in a similar manner. You will then see a round cover on the floor with a number of screws. Remove this cover to access the top of the fuel tank. Use a BRASS punch to rotate the locking ring and then remove. You can then remove the fuel level sending unit and fuel pump as one unit.

Don't buy a full time 4x4. This just means you cant turn 4 wheel drive off. Go with AWD if possible. some suggestions would be an Subaru outback, and most crossovers.
If it is fuel injected the fuel pump will be located inside the fuel tank.
They do, but you will have to pay full charge again.
Give it a full tune-up.
