How do you change the fuel sending unit on a 2003 duramax diesel


2 ways this can be done 1 lift the bed of the truck offso you can get to the top of the tank where the sender is located ( 8 bolts 4 on each side, three 9/32 screw aound filler neck and 1 or 2 plugs for tail lamps. Th other option is to drop the tank down by removing filler neck hose from tank and 2 straps held in with 15 mm bolts , It would also be helpful if the tank is as empty as possible...good luck

How do i replace the fuel level sensor on a 2005 kia sorento


What You'll Need:
  • flat head screwdriver
  • Phillips head screwdriver
  • hammer
  • open end wrenches
  • replacement fuel tank sending unit
    Before you begin, disconnect the negative battery cable to be sure no electrical sparks are possible. You're dealing with gas which is highly flammable!Your fuel tank sending unit is located in the top of the fuel tank, but is accessible under your back seat (or under the carpet in your trunk) on some models. The sending unit will be protected by an access cover, usually held on with a couple of screws. Lift your back seat or trunk carpet and locate the access cover for your fuel tank sending unit. Remove the screws holding the cover in place and remove the access cover to reveal the fuel tank sending unit.
    Safety Note: Gasoline is highly flammable. By removing the fuel tank sending unit, you are opening the gas tank. Be sure there are no sources of spark or flame nearby.
    With the access cover removed, you'll see the fuel tank sending unit right there on top. It will have a wiring harness plugged into the top (this tells your gas gauge how much fuel is in the tank). Unplug the wiring harness and move it safely to the side. If your fuel tank sending unit is screwed or bolted in place, remove the screws or bolts. Some sending units are a "twist-lock" type. They work like the old twist-lock gas caps. You'll see a few notches along the outer ring of the sending unit. Place the tip of a sturdy flat head screwdriver in the notch and gently tap it counter-clockwise. The sending unit will rotate until it's loose. (the picture above shows the fuel tank out of the car to illustrate the fuel tank sending unit's location). Now you can remove the fuel tank sending unit in one piece. Attached to it is a long rod with a float at the end, so you might have to try a couple of different angles to get it out. As usual, installation is the reverse of removal. Don't forget to plug the new sender in or it won't send you anything!

My fuel gauge is blinking an my fuel indecator is showing my tank is empty, after I fill up the tank. How do I fix this problem?


The problem would be a defective fuel tank sending unit. The fuel tank must be removed to replace it. Some sending units are serviced only as a complete fuel pump and hanger assembly. Check with your dealer to see if the sending unit is available separately or if you must buy a complete fuel pump module.

The low fuel light stays on even when tank is


Hi: Your Fuel Level Sending Unit That Is Located in Your Fuel Tank Is Probally Bad. BUT before you go to taking the Sending Unit out Of your Tank Check to see if ALL Connections To And From Tank to Gauge are Conected Good. Also You could have a Fuse that Goes to the Sending Unit,in Your Fuse Block.Check And See if You Have A Fuse Labeled Fuel Sending Unit or Fuel Sensor. If you end up Replacing The Fuel Tank Sending Unit Run Your Gas Tank Down To Almost Out Of Gas Before You Start to Remove The Metal Straps Holding Your Tank Up. Cause The Sending Unit Is on Top of Your Tank ,And Your Fuel Pump Is In The Gas Tank As Well.
