Gas tank floats all over the place on my 2005 halibut. I was told there may be access from under the rear seat in order to replace the part in the tank instead of having to drop the tank. Is this true? Also, my right directional bulb keeps blowing.

The fuel meter inside the tank has malfunctioned. One option is to replace the fuel pump. Second option is to bring down the fuel tank and remove the fuel pump and check see if the metering rod was bent. Now if you are not having problems with the fuel pump. I would deal with the gauge being low and continue running the car until the time comes to replace the fuel pump.

The fuel pump is in the gas tank and access in inside the van between the first row and second row of seats. The access is covered with a carpeted cover and then another metal cover which screws into the gas tank. Then there is a cover top of the assembly.

You must use a brush and clean off all the areas before removing the pump or the dirt will get into the gas tank. Disconnect three electrical connectors and two fuel lines. Mark the fuel lines so you are not confused to put in the new one. The electrical conectoers are individually different from each other.


2005's do not screw into the tank, they have clips. The clips have tabs imbedded into the top so you know where they are located to disengage them.

The tank lifts out and the float mechanism requires you to live it up and then tilt and shift it to get the float mechanism clear of the gas tank hole.

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!
  
  

Go to www.hmaservice.com and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, campaigns, illustrations and procedures, etc.

Go to Fuel Pump (FP) under Shop Manual. Illustration shows access place under rear seat bottom. Removed Rear Seat Bottom... you'll see floor access plate ... remove plate to access fuel pump.

it is inside the gas tank, part of the sender unit. you have to take the tank out of the car in order to replace it. while it is out of the car do yourself a favor and replace the fuel pump too so you do not have duplicate labor when the pump goes out next year. before you go nuts, pull the liner or carpeting out of the trunk and make sure your car's trunk does not have a service access to the gas tank.
generally gas tanks are mounted under the trunk.

no, there is an access panel under the rear seat-remove the bench and the top part of the seat in the rear and pull back the carpet-there is a inspection plate that is screwed into place above the fuel pump.

It is behind the rear seat cushion and the access panel. To do this open the rear doors on the 2005 Hyundai and locate the two main connector bolts that hold each rear seat in place. The two bolts are located under the front part of each rear seat. Remove the four bolts with a 3/8 inch ratchet and a 12mm socket. Turn the bolts counter-clockwise to loosen and remove the bolts. Slide the rear seats out of the seat compartment. Then slide the rear seats out of the car. If you want do some more intricate work like replacing the filter then follow this link.

It is most likely your fuel level sending unit has gone bad. It sits inside your fuel tank and uses a float similar to that uded in your toilet to tell the fuel guage how much gas you have in the tank.

In many cases, the unit can be accessed for replacment by removing the rear seat and opening the access port (3-4 screws) and removing the sending unit from the top of the fuel tank. It looks like this...

The Sorento gs tank is under the floor in the back seat. Flip the seat bottom's forward and pull open the Velcro to access the top of the tank. The fuel pump and sender may be accessible from the top, but you might be unlucky and have t remove the tank.

The tank does not need to be dropped. There is a access panel either under the cushion of the rear seat or in the trunk. I have to replace the pump on my 02
