I would recommend taking off the tank all the way i do not know the reason why you haven't done it but i assume is the fuel lines they take a special disconnecting tool but it is not expensive at all an auto parts store may have it under 10$ if it is another reason then you can just let me know and i can help. the lock ring has a few edges where you can use a hammer and chisel or screw driver and make it turn counter clock wise and reverse this procedure to instal make sure the tool you use is not very sharp and let me know if this helped or need further assistance thanx.

Fuel pump replacement


For the 2000 Grand Am, the fuel pump is replaced by draining the fuel tank or having it as empty as possible....then (while on jacks) lower the fuel tank. Remove the harness and the tubes to the top of the sending unit. Remove the lock collar ring that holds the pump in place (sending unit is mounted to the side of the fuel pump) and lift out the pump assembly...tilting it slightly (it has fuel in it so watch for it to spill out) and slowly so as not to damage the float internally.
Installation is in reverse. Sounds easy but there is more to it because of the lack of space between the tank and the underside of the car...trying to disconnect these items.

Replace a fuel pump on a 1996 cevrolet S-10 4 cylinder


the fuel pump is located inside the fuel tank.

  • Park your Chevy S10 in a safe place with a level surface. Make sure you have enough room to work around the truck.
  • 2 Unplug the fuel pump relay, which is located in the fuse/relay box in the engine compartment on 1995 to 1997 2.2L engine models. Markings on the relay or the back of the fuse box lid should identify the relay. On other models, press the small stem inside the Schrader valve--similar to a bicycle-tire valve--located on the fuel inline rail, right before the first fuel injector. Cover the valve with a shop rag as you depress the stem with a small screwdriver to catch the squirt of fuel.
  • 3 Disconnect the black, negative battery cable and raise the rear of the truck with a floor jack. Safely support it on two jack stands.
  • 4 Drain the fuel tank into an approved container through the filler pipe. Use a hand siphon pump if necessary.
  • 5 Disconnect the clamp from the filler hose at the tank with a screwdriver and remove the hose. Remove the tank shield. Support the fuel tank with a floor jack and a piece of wood on the jack pad to avoid damage to the tank.
  • 6 Remove the tank-holding straps with a ratchet and socket.
  • 7 Lower the fuel tank so you can disconnect the fuel lines from the fuel pump/sending unit assembly on top of the tank. Unplug the pump electrical connector and lower the tank to the floor.
  • 8 Turn the lock-ring tabs holding the pump/sending unit assembly to the tank counterclockwise with a drift punch and a soft hammer until the ring is released.
  • 9 Lift the pump/sending unit assembly off the tank, remove the pump and install the new pump in the pump/sending unit assembly. Discard the pump/sending unit O-ring seal.
  • 10 Install a new pump/sending unit O-ring and set the pump assembly in the tank.
  • 11 Lock the assembly lock ring by turning the ring clockwise until it locks in place.
  • 12 Connect the fuel lines to the to the fuel/sending unit assembly and plug the pump electrical connector.
  • 13 Raise the tank to its mounting position and install the tank-holding straps. Install the tank shield and connect the filler neck to the tank.
  • 14 Lower the truck, plug the fuel-pump relay and connect the black, negative battery cable.
  • 15 Refill the fuel tank, start the engine and check for leaks.

    How hard is it to change the sender in the gas tank?


    It's not really hard, but it can be potentially dangerous. Especially if you don't have a jack to lower the fuel tank. Each tank also has a slightly different locking ring for the sender as well. They're usually not that hard to get apart, but there's potential for sparks and explosions. It's always much easier if you have a nearly empty fuel tank, but keep in mind the fumes are flammable. Usually there are two straps that hold a tank in place. Remove the straps, lower the tank part way, disconnect fuel lines and wires, then lower all the way. Slide the tank out from under the vehicle. Unscrew the locking rings, remove the sender. Make sure the area is clean first, you don't want any dirt getting into the tank. Pull the sending unit out and replace the faulty part. Reinstall exactly as you removed it.

    How do you replace a fuel pump on a 1999 chevy blazer


    Relieve the fuel system pressure if any. Wrap a shop rag around the Schrader valve located on the inlet fuel line of the fuel rail, right before the first fuel injector-the valve is similar to an air valve on a bicycle tire; then depress the small stem inside the valve using a small standard screwdriver to free the fuel form the line.
    1. Disconnect the black, negative battery cable; raise the rear of the vehicle using a floor jack and safely support it on 2 jack stands.
    2. Working from underneath the vehicle, disconnect the filler hose form the tank by removing the hose clamp using a Phillips screwdriver or ratchet and socket; then remove the Fuel tank shield using a ratchet and socket. Support the fuel tank with the floor jack and remove the tank mounting straps using a ratchet, ratchet extension and socket.

    Lower the tank carefully, just enough to disconnect the two fuel hoses and vapor hose from the sending unit/pump assembly on top of the fuel tank. Press the lock tabs on the hoses connectors and pull the hoses form the assembly fittings; unplug the fuel pump electrical connector and lower the tank to the floor.

    Remove the lock ring from the sending unit/pump assembly using a drift punch and hammer. Carefully rotate the lock ring tabs counterclockwise with the drift punch and hammer until the ring is free from the assembly. Lift the sending unit/pump assembly off the tank and out of the vehicle.

    Install the new pump on the sending unit/pump assembly. Make sure the pump filter is in a horizontal position and does not interfere with the travel movement of the sending unit float arm; then install the sending unit/pump assembly into the tank using a new O-ring between the assembly and the tank.

    Secure the assembly in place by turning the locking ring clockwise using the drift punch and hammer; then raise the fuel tank enough to connect the fuel and vapor hoses and plug the pump electrical connector.

    Raise the fuel tank, install the tank mounting straps and tank shield; connect the filler hose to the tank and lower the vehicle; install the fuel pump relay and connect the black, negative battery cable. Start the engine and check for fuel leaks.

    Good luck and hope this helps. It's about a 4 hour job from start to finish, also if your going to go through all that work. Buy a wire harness from the fuel sending unit to the frame. It's only around $15.00 and who knows, it may just be a bad wire harness that may be the problem.
