Fuel sending unit

[2000Yukon]

My gas gauge has been acting up lately, it will be clear full, shut it off and start it again and it will read empty and the message center will display low fuel.

Or it will say its empty message center displays low fuel, back down my driveway and will go back to full.

Could it be the sending unit in the tank, or my cluster?

I'd bet my money on sender assembly

Anyone have any idea how much it is to fix?

Well with mine the fuel pump was going bad, I had to get a new fuel pump which came with the sender unit. With labor it was $600+. I think you can get the sender unit by itself for $200+, the labor to put it on is pretty high because they have to drop the tank.

If I were to do it myself, is it pretty straight forward? Very hard? Time consuming?

If you know someone with some mechanical skills you can DIY, not sure how hard but time consuming yes. Gotta have something to put the fuel in, getting the tank off is probably going to be the hardest part but can't say for certain. Definitely have someone help you.

Thanks for the help.
