More than likely it is a vent or overflow hose. It probably connects to a fitting toward the top of the tank.

SOURCE: The fuel tank on my 2003 Tahoe will not take any

Yes, it could simply be an air-lock, but it could be that the fuel gauge is mis-reading too. The bottom of the tank may even be damaged, that is pushed up by a mis-hap of some sort. If filling the tank slowly doesn't solve the problem, I think I would dip the tank using a fexible tube. At least that wiould tell you if the tank is 1/4 full or not.

SOURCE: 2003 5.3L Chevy Tahoe. The fuel pump needs replaced

The connectors tend to get dirt and debris in where the special tool slides in which prevents the little tabs from disengaging from the raised ring on the plastic pipe. Pull the line towards the pump as if you were trying to push it on even further and use compressed air to blow out any crud where the tool goes. Then insert the tool and push it in firmly while pulling the line toward the tool a bit to relieve the pressure on the little internal metal retaining clips and at that point with a little wiggling the line should come off. I've taken off dozens and they can be exasperating to say the least. IF all else fails and you are certain that you are going to replace the pump module and absolutely can not get the lines disconnected for the stubby plastic fittings on top of the old one then you could simply break off the plastic fittings on the old pump so you can work on getting the fittings disconnected once you have the tank out. I've had to do this a couple of times but it means that the old pump module can't be used again since the fittings would be broken off of it. Be extremely careful working around the tank as it will be full of gasoline fumes and extremely flammable!

Remove fuel pump from gas tank on 96 chev Tahoe 4door

You have to drop the fuel tank carefully (easier to do if the tank is empty). Disconnect hoses and wiring connectors from the pump/fuel level sensor. Vacuum or brush off any debris on the fuel pump and around the locking ring. Remove the locking ring and wiggle the pump assembly out.

Need to know how to disconnect the fuel lines from the fuel pump to replace the fuel pump

  • Park your Chevy Tahoe in a safe place with a level surface and plenty of room for you to work around the vehicle. Open the hood and disconnect the black, negative battery cable.
  • Relieve the fuel system pressure. Loosen the fuel filler cap and depress the small stem inside the fuel pressure Schrader valve. The valve is similar to an air valve on a bicycle tire and is located on the fuel inline rail in the engine compartment right before the first fuel injector. Use a small screwdriver to depress the stem while covering the valve with a shop rag to catch the squirt of fuel.

  • Drain the fuel tank through the fuel filler hose using a hand siphon pump if necessary.
  • Raise the rear of the vehicle using a floor jack and safely support it on two jack stands.
  • Remove the evaporative emission (EVAP) canister located next to the fuel tank. Use a wrench or ratchet and socket.
  • Disconnect the chassis fuel lines leading to the fuel tank by pressing the lock tabs and pulling the lines off their fittings. Plug the fuel lines with clean shop rags to prevent fuel system contamination.
  • Disengage the EVAP line from the clip at the side of the tank, opposite the frame rail. Support the fuel tank with jacks if necessary and remove the two fuel tank straps using a ratchet and socket; then lower the rear of the fuel tank slightly. If necessary, disconnect the fuel filler hose from the tank by removing the hose clamp at the tank.
  • Disconnect the fuel pump electrical connectors, lower the tank and disconnect the fuel lines from the fuel/sending assembly on the tank.
  • Clean the area around the pump/sending unit assembly. Disconnect the pump/sending unit by unlocking the cam lock. With a long punch and a light hammer, turn the cam lock counterclockwise. After releasing the cam lock, lift the pump/sending unit assembly off the tank and replace the old pump with the new unit.

    2004 Dodge 2500 diesel loses power while driving.

    either your fuel guage is not reading properly and you have less fuel than you think or your fuel pickup nedds to be adjusted sometimes the pickup looses the ability to pull the fuel from a certain level which would indicate that the pick up is going bad or is already bad if you replace just the pickup see if you can get one thats a little longer than the one that you have already so that it can go deeper into the tank. maybe the pickup tube has fallen off also and the pump can only pull the fuel when the tank is full. hope this gives you some ideas as to where to start.

    Very slow to fill fuel tank. refuel hose nosel keeps clicking off when refueling

    on your fuel tank their is a vent line from the tank that comes back up to the main fuel inlet line that is to let the air from an empty tank escape while fuel goes in, if that vent is not working properly then the fuel cannot go in quickly because the air in the tank has no where to go. The hose is made of rubber and may have become fatigued and kinked on a sharp corner. You will have to go underneath the vehile and inspect where vent line from where it exits the tank and goes back up to the main inlet line. You may have to replace the line.

    My fuel level indicator gauge doesn't show the accurate fuel level. How much would it cost to fix this? I fill the tank up and it works pretty well until 1/2 tank, then I don't know how much fuel I have....

    What this sounds like is the sending unit in the tank needs to be replaced. Call the dealerships around your area to get an idea on price. I think the gas tank has to come down.

    Fuel pump removal 96 nissan quest

    Replace Fuel Pump for 1997 Nissan Quest

    (1) If the fuel tank has more than one third full, you need to get the gasoline out. If it has one third or less full, you can leave it in the tank. However be very careful around the working area. Make sure you have read fire precautions in a general repair book. Take the fuel pump fuse out from the fuse box near the battery. Run starter for a few seconds. This will remove the fuel pressure in the gas lines. Disconnect battery at negative terminal. Jack up the rear of the van.

    (2) Remove the fuel tank protector.

    (3) Disconnect fuel pipes at the front end of the fuel tank. Use short pencils and extra rubber hoses to block disconnected pipes and hoses.
    59aa089.jpg There are two pipes connected to the gasoline filler at the side of the van. Disconnect only the smaller one. The larger one is flex enough for the tank to be lowered.

    (4) Disconnect the electrical from this connector. Jack the rear end of the fuel tank with a car jack and a piece of 2x4. Put the wood between the jack point and the tank. Then unbolt the two bolts showing in the picture.
    (5) Lower the jack after the bolts are removed. The rear end of the tank should be lowered.


    (6) Disconnect fuel lines on top of the fuel pump. Reconnect each short hose back to different pipes as shown in picture to block the pipes.
    (7) Loose the six mounting bolts on the fuel pump assembly. The bolts should be loosen a little at a time in multiple turns. Also detach the electrical wire holders. After all bolts are removed, carefully take the assembly out of the tank.

    (8) Remove the fuel pump from the assembly as shown in picture. Then unplug the electrical wires. Note that two connectors are in different sizes, so that you will not be able to reconnect to a wrong terminal.
    (9) Put the new pump and new filter in. Reconnect the electrical wires. If necessary use a pair of pliers to make the connectors tighter. Make sure they are not loose. Reconnect gas inlet to the pressure regulator.
    (10) Use a new O ring, put back the assembly to the fuel tank. Make sure the float of the fuel level senser is free, and the assembly is at the right orientation (as shown in picture). Screw back the 6 bolts after making sure the O ring is in right place. The bolts should be tightened in turns. Do not over tighten them. Then reconnect the fuel lines and make sure every fastener is tight. Put the electrical wire into holders.
    (11) Jack up the tank and put the two mounting bolt in. (see picture in step 4). Make sure they are tightened with specific torque. Reconnect the electrical connector.

    (12) Reconnect two fuel lines at the front side of the tank. Refer to the picture in step 2. Reconnect the hose to the gasoline filler. Before you have a try start, double check if all fuel lines are securely connected and tightened.

    (13) Start the engine. You need to crank more than a normal start because the lines were empty. The pressure is built up in some time.

    (14) If engine starts ok, turn it off. Then check under the van if there is any leakage. If everything is fine put back the tank protector. (picture in step 2).
