Removal & Installation

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Remove or disconnect the following:
    • Negative battery cable
  3. Relieve the fuel system pressure.
  4. Drain the fuel tank.
  5. Remove or disconnect the following:
    • Fuel tank

    WARNING Do not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage tool Joints.

  6. Disconnect the fuel and evaporative emission (EVAP) lines from the fuel tank module.
  • Fuel sender assembly retaining ring using a fuel tank sending unit wrench. Remove the fuel sender assembly and the seal. Discard the seal.
  • Note the position of the fuel strainer on the fuel sender. Support the fuel sender assembly with one hand and grasp the strainer with the other hand. Pull the strainer off the fuel sender. Discard the strainer after inspection. Inspect the strainer. Replace a contaminated strainer and clean the fuel tank.
  • Fuel pump electrical connector
  • Electrical connector retaining clip from the fuel level sensor
  • Sensor electrical connector from under the fuel sender cover
  • Fuel level sensor retaining clip
  • Squeeze the locking tangs and remove the fuel level sensor.
  • Remove the fuel pressure sensor.
  • To install:
    1. Install or connect the following:
      • Fuel pressure sensor
      • Fuel level sensor
      • Sensor retaining clip
      • Electrical connector to the fuel level sensor
      • Electrical connector retaining clip to the fuel level sensor
      • Fuel pump electrical connector

      NOTE Always install a new fuel strainer when replacing the fuel tank fuel pump module.

      • New fuel strainer in the same position as noted during disassembly. Push the strainer on the bottom of the fuel sender until the strainer is fully seated.
      • New seal on the fuel tank

      NOTE The fuel pump strainer must be in a horizontal position when the fuel sender is installed in the tank. When installing the fuel sender assembly, assure that the fuel pump strainer does not block full travel of the float arm.

      • Fuel sender assembly into the fuel tank
      • Fuel sender assembly retaining ring
      • Fuel tank. Install the fuel tank strap attaching bolts. Tighten the bolts to 30 ft. lbs. (40 Nm).
    2. Refill the fuel tank. Install the fuel filler cap. Connect the negative battery cable.
    3. Turn the ignition ON for 2 seconds.
    4. Turn the ignition OFF for 10 seconds.
    5. Turn the ignition ON.
    6. Inspect for fuel leaks.

    2004 yukon xl bogging down when acclerating rapidly


    Maybe change your fuel filter if it has not been done for a while and might have to get your fuel pressure tested. The pressure needs to rise when you romp on the throttle and if it does not that could be a problem with maybe the fuel pump or regulator.

    My 2002 GMC Yukon Denali's fuel guage goes up and down sometimes. It is not always reading correctly. Is this a sensor problem or a fuel pump problem.


    Most likely the rheostat on the float is bad. Unfortunately, this is part of the fuel pump and inside the fuel tank.

    02 yukon denali xl wont start, i replaced battery, alternaor and starter are both good truck still wont start


    Did you try to replace the starter cable? is the Truck turning over or just clicking.? If it's turning over and not starting. Best guess would be one of two things. Knock sensors Located under intake manifold. they get wet and deteriorate or the fuel pump. I've replaced all three on mine. 233k still running strong...
