Can the fuel pump be changed without dropping the fuel tank? I have a manuel that says the fuel pump can be removed from the rear luggage compartment. I just don't see how.

The fuel pump is located in the tank, under the rear cargo floor. Begin by removing the six phillips screws in the plastic trim at the base of the rear door. Set the trim aside, and pull up the carpet and insulating pad. The corner trim may need to be pried upward to allow access to unseat the carpet and pad from the anchors in the rearmost corners.

Carpet flipped up. Pad was previously removed due to a water leak, which led to an unpleasant surprise. The hatch in the cargo floor which provides access to the pump. The old pump installed in the tank.

Remove the six phillips screws which secure the hatch above the pump. Set aside, and be sure to clean the area around the pump prior to removing the pump. This will ensure no dirt or other elements fall into the tank during the course of the work.

Remove the electrical connector from the pump. Use one 14mm box wrench to hold the fitting on the fuel line, and use the other to loosen the fitting on the pump. Loosen and pull away both the return and feed lines.

Loosening the fuel line fittings with two 14mm box wrenches. The old pump is ready to be removed after a thorough cleaning of the area.

Remove the plastic securing ring from the pump and tank. Carefully pull the pump straight up and out of the tank until the fuel level sensing mechanism contacts the top of the tank. Slowly tip the pump to drain as much gas from the pump assembly as possible, then work the pump out of the tank without bending the level rod. The tank seal will likely remain on the pump. Remove this seal and reinstall to tank (or use a new seal), with the uppermost ridge seated above the lip of the tank.

I can not find the six phillips head screws in the trim.

Why are you changing the pump and be specific cause you may not need to based on the wrong diagnois.
