Yes, you DO have to drop the fuel tank to remove the fuel pump module assembly! Things You'll Need Floor jack and 2 jack stands Wrench set Ratchet and socket set New fuel tank mounting studs Park the vehicle in a safe place and make sure there is enough room around the back of the vehicle for you to work and move tools around. Start the engine and let it idle while you relieve the fuel system pressure by removing the fuel pump fuse or relay from the fuse box. Wait a few seconds for the engine to stall, turn the ignition key off and replace the relay or fuse. Raise the back of your car using a floor jack and support it safely on jack stands. Disconnect the fuel tank filler pipe and the fuel pump connector located above the cross member underneath the vehicle. Disconnect the vapor tube from the tee connector on the right side of the car-passenger side-and the vapor line from the canister tube. Support the fuel tank with a jack and remove the nuts from the holding strap using a wrench or ratchet and socket. Move the strap away and lower the fuel tank. Discard the fuel tank mounting studs. Unplug the pressure transducer electrical connector located on the top rear corner of the fuel tank. Clean the area around the fuel pump mounting flange and remove the flange mounting bolts in a crisscross pattern. Lift the fuel pump assembly off the tank. Replace the new fuel pump in the assembly and install the assembly in the tank. Install the flange screws and torque to 89 inch lbs. (10Nm) using a crisscross pattern.
