yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

the fuel tank must be removed from the vehicle to replace pump or lift the box from the frame. If you remove the tank it is held up with two tank straps and the lines must be unhooked as you lower it. good luck unless you have access to a lift.

ok i'm going to guess that you have a gasoline engine with a side tank like in a pickup truck. if you have a diesel let me know, things might be a little different. here's the step by step for a gas side tank. before you start, disconnect the battery negative cable.
1. drain the fuel from the tank (they don't tell you how, just get as much out as you can)
2.raise and safely support vehicle (get it high enough that you can get under it to work on it)
3.loosen the fuel neck hose at fuel neck and disconnect filler neck from tank
4.support tank and remove tank support straps and insulator strips
5.remove frame mounted bracket
6.lower fuel tank shield
7.lower fuel tank enough to gain access to fuel and electrical connections
8.disconnect fuel feed and vapor hoses
9.disconnect electrical connectors
10.remove fuel sender assembly and seal ring
now to install new tank
1.install NEW seal ring and install sender
2.raise tank enough to connect fuel feed /vapor hoses and electrical connector
3.raise tank fully
4.install fuel tank shield
5.connect fuel tank filler neck and tighten clamp
CAUTION tighten fuel strap fasteners in steps, alternating between straps, until proper torque is reached. failure to properly follow this step can cause bottom of tank to deform. fuel gauge may read improper level if this occurs
6.install fuel tank brackets and insulator strips
torque nuts to 115 in-lbs
7.install fuel tank filler cap
8.connect battery negative cable
9.turn ignition switch off and on and check for leaks
it's pretty much the same for rear tank, just different location, may have off-road shield in back and torque spec is 47 ft-lbs, not 115 in-lbs. you still have to alternate when you torque straps or you risk deforming tank. hope that helps

Evap vent solenoide is stuck closed. Start by replacing the valve and checking the hose to the valve for clogs...this is located between the cab of the truck and the bed of the truck on the driver side (can be seen if you look down through the crack)....If this doesn't work then check the fuel filler neck hose for kink or restriction this is the hose that goes from the gas cap to the fuel tank.

My 2002 Impala has the panel in the trunk. I took the panel off and the fuel pump is accessible. I will probably attempt to replace the fuel pump myself since the fuel gauge does not work anymore and the dealership indicated that the problem was the fuel level float connected to the fuel pump.
Does anyone know if there is anything special I need to do prior to replacing the fuel pump, such as draining the fuel, etc...? I was planning to at least run the car until I was near empty.
FYI, here is a link to a set of videos about replacing fuel pumps. It's a set of 13 short video clips. http://www.wonderhowto.com/how-to/video/how-to-repair-or-replace-a-fuel-pump-226058/
