Bad fuel sensor/sender?

[Southpaw]

Ok Help me out guys,
My fuel gauge has been stuck at full for a long time now(way longer than I am going to admit to). With all my back problems lately, I haven't been able to drop my tank yet. I'm getting ready to do it within a couple weeks now though.

The gauge has been stuck at full forever, but now it goes back and forth. I will be driving and it will drop to empty and the light and the tone come on(freaks my wife out ). Then later it will go all the way up to full again. I checked the plug on top of the unit, and it seems to be making a good connection, so I guess it's a problem in the tank. It also throws a P0460 code, which is the fuel level sensor.

I have seen that whole unit that comes out of there....but what needs to be replaced? Fuel sensor? Fuel sender? Is there such a thing as both of those, and what's the difference? Has anyone had this problem, and know the exact fix and what to buy? Thanks guys...

While i'm in there, I will probably be doing the pre-pump filter, and the harpoon mod.

Sending unit may have gunk on it or is rusted out. I don't know how much for a new one.

Is the sending unit that entire sutup that comes out of the tank, or just a peice of it?

[Southpaw]

has anyone has this same problem, or replaced this?

It isn't REAL common. I'll dig around for some in tank pics. Search for AlabamaFrog. I think he had some good pics.

I have seen lots of pics. I was just curious...is the whole thing bad? or does just one or more peices of it need to be replaced?

I'm going to research it more....
Thanks Dirk

I just had that code come up yesterday though my fuel gage has been working correctly for several months since I purchase my excursion. I guess it may get stuck at 3/4 of tank since that is what it was at when the code fired up. If you find anything else out let me know.
