Back on the driver's side...

Connect the two fuel lines inside the fuel tank to the fuel filter assembly.

These lines are different sizes so you can't mix them up.

Again, press these lines on until you hear or feel a click. You shouldn't be able to remove the hose by pulling on it (unless you press the release tab).

Place the new gasket in place on the fuel tank as shown. Clean the mating edge of the fuel tank first so you get a good seal.

Continue connecting the electrical connections to the fuel filter assembly. These connections should be the same as when you removed the original fuel filter assembly.
