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

Check in relay box on passenger side near firewall for fuel pump relay.
By -pass, no such luck that I' aware of, sorry.

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

possible fuel gauge malfunction but its a chevy.
over the past year chevrolet fuel pump failure has increased by over 900% the fuel level sending unit is incorperated in the fuel pump module,
these fuel pumps do not like fuel additives nor do they tolerate E85 fuels.
you will need to replace your fuel pump assembly, try to locate a carter brand pump they are very reliable.
as far as replacement.
just open the fuel filler door remove the two torx screws and one push pin from the fuel filler neck, go under the truck at the back of the bed on the frame cross bar and unplug the bed plug, remove the 8 bolts that attatche the bed to the frame and the one ground wire under the bed by the fuel filler neck. get a budy and lift the bed off of the frame, now you can access the top of the fuel tank for the pump replacement. dont get discouraged it is a easy fix, i can do these in under an hour.
