Removal & Installation
The fuel pump is located in the fuel tank. The fuel tank must be removed from the vehicle in order to access the pump.
Properly relieve fuel system pressure.
If not already done, disconnect the negative battery cable.
Raise and safely support the vehicle.
Safely drain and remove the fuel tank assembly, as outlined later in this section.
If necessary, detach the quick-connect fittings from the fuel sender assembly and remove the fuel lines.
Remove the fuel gauge sender and pump assembly by turning the cam locking ring counterclockwise. It may be necessary to use a spanner wrench, such as tool J-24187, to perform this.
Carefully lift the assembly from the fuel tank, then remove the fuel pump from the fuel gauge sender unit.
Remove the sender O-ring from the top of the sender and discard.
Disconnect the pump wires, hose clamps and the clamp from around the pump body.
Pull the pump assembly out of the rubber connectors.
Inspect the fuel pump attaching hose for any signs of deterioration, and replace as necessary.
To install:
Push the fuel pump assembly into the attaching hose. Attach the pump electrical wires and fasten the hose clamps to the attaching hose and around the pump body.
Place the fuel tank sender and pump assembly into the fuel tank. Use a new O-ring seal during assembly.
Place the cam lock over the assembly, then lock by turning clockwise, using a suitable spanner wrench, if necessary.
If removed, attach the fuel sender fuel line quick-connect fittings.
When installing the fuel tank, make sure all rubber sound isolators or anti-squeak spacers are replaced in their original locations.
Install the fuel tank, as outlined later in this section.
Refill the fuel tank.
Connect the negative battery cable.
Turn the ignition switch to the ON position to pressurize the fuel system and check for leaks.

Only two are fuel lines, the main feed to the engine and the return line from the engine to the tank. One other gas tank line will be the EVAP line for sending gas tank fumes from the charcoal canister to the engine's intake manifold.
I think the other lines would be your brake lines to the rear wheels.
YouTube has many videos on repairing rusted fuel lines. Most people use the lines made of plastic in their repairs-takes special fittings though. These plastic lines have become very common now. In fact my '92 LeSabre has mostly plastic lines.
there is a pressure regulater on the fuel line under hood replace it if you have already replaced fuel filter.if that dont work you may need to replace your cadelistic converter on you exsost
