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

SOURCE: i am trying to remove my fuel tank from a 96 chevy suburban and replace the fuel pump

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

SOURCE: fuel guage on my 2006 chevy trailblazer stopped

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.

I have a 2000 gmc 3500hd,the fuel gauge stopped at half way and i run out of fuel. the rear tank is not sending fuel to the front tank?


David Johnson is wrong about that. The Chevy HD dual tank has two sending units, one in each tank , one fuel pump, a fuel pump relay switch and a equalizing pump. If the truck stalls out at 1/2 tank, it is the equalizing pump. That pump, pumps fuel from the rear tank to the front. If the pump is out, the front tank empties, the truck shuts down, the guage reads half tank because the back tank is still full, but the equalizing pump won't pump the rear fuel tank load to the front. Hence the problem you listed above, not a sending unit.

Fuel guage drops to empty then back up, wont take gas in tank


The fuel guage could be a faulty fuel sender unit or possibley an electrical fault in the dash.
The only reason I can think of that it won't take gas is that it is full. You could try pulling the filler nozle out a couple of inches when you are trying to add fuel. . They work on back pressure , and if the pressure backs up , the pump handle clicks off.

Where can I find a fuse for the gas gage on a 2004 Chrysler T&C


The gas guage does not have its own fuse but instead gets its power from the "integrated power module" that handles power delivery to the entire instrament cluster and beyond. If the guage is in-op,[doesnt work] then you will need to have a few "hands-on tests run to verify if the sending unit in the tank[fuel pump module] is functional or if this problem lyes else-where, wiring problem, bad ground,ect,ect.. One hint would be if the low fuel level l;ight still functions without the fuel guage working,then your problem is NOT in the tank and very likely is in your dash-electrical or faulty guage.

2004 Chevy Malibu. Cranks but won't start up. Where is the fuel pump located? Where is the fuel tank located?


The pump is in the tank, the tank is in the rear (follow the big hose from where you fill it up) but dont just go put a pump in, check fuel pressure and make sure the pump is indeed getting power before replacing it. I cant tell you how many people replace a pump for no reason. I would have a shop check it for you.

Why does the gas guage not register how much gas is in the tank of our 2001 Chevy Impala?


This could be due to a faulty fuel sensor in the fuel tank try draining the fuel tank and replacing the sensor.

1982 Chevy K10 Fuel Problems


Check to see if timing belt is broken. or wiring to crank-shaft sensor and check sensor itself on front of flywheel typically but may be on side of block usually the further towards the transmission is Crank and closer to front is cam sensor.

Check relays by switching from others of the same numbers.
Crank-shaft positioning sensor is bad perhaps.
Remove plug under vehicle that leads to fuel pump and check for voltage when key is turned on. if voltage is there is either defective fuel pump, was put in wrong or is harness from that point to the pump.
try banging the tank with hammer as someone turns key on.
 check harness from fuel pump to where it goes into the body - remove from body plug and inspect.
Should be either and or both a fuel pump relay and fuse! 
Run 12 volts to the positive side of the fuel pump wiring to see if pump is good. 3 wires usuallly  1 is ground for both the fuel guage and the other positive for the pump. and other is positive for the fuel pump guage and these two wires for the guage will show some resistance. put a fuse inline with the 12volts to the fuel pump positive but cut the line to the body prior to this - temporarily.
Could be bad switch in ignition unit in steering column but doubtful.

Hope this helps.

Gas hand for 2004 chevy cavalier won't work. how can i fix this? thanx


i don't have a terrible amount of experience with fuel guage systems, but, from what i understand there is a little bobber in the gas tank which is connected to the fuel pump.

I've heard that the wires are generally exposed and can get corroded and either cause it to give "jumpy" readings or no readings at all.

I suppose it wouldn't hurt to pull it out and take a look at it..., although i'd probably check for continuity (use a digital multi meter) from the wires ends connecting the guage to some part of the wires near the fuel tank so that you know if the wires are broken/shorted before you ripping into the tank to check the pump.

Hope this helps,
Thomas

2002 chevy duramax fuel gauge stopped working and makes vibrating noise sometimes around back fuel tank is this a simple fix and how thanks


Well I have a 2002. I have had this prob from the day I drove it home from the dealer. Evry time I'd put fule in the rear tank the guage stopped working. The transfer pump stopped working. It was back at chevy (3) times, and still no fix. They keep puting in new rear transfer pumps in it but that is not doing it.
It is an Electrical Problem, I keep geting rear transfer pump codes. So I was just unhooking the bat's but it's a pain.
So I just stopped puting fuel in the rear tank. And now if it stops working I just us the scanner to clear the codes and it will start to work... I am so done with this truck.
This truck also had ( whater pump, (2) Glow plugs, Injectors, fan cluch,) all go out in the first (5) years. GM, Is trash...

I have a 2000 Chevy 3500 box truck with 2 gas tanks. The gas guage only goes to 1/2 with both tanks full and it won't pump gas from the second tank. How do I fix this.


Fuel levels are equaled in the tanks via a frame mounted transfer pump that transfers fuel from the rear tank to the front tank where the main pump is. Your transfer pump needs replaced, and should run about 60 bucks. Should find the pump mounted to the frame between tanks.
