Sender or dash gauge??

Dash gauge. Tough to tell on the video.... is it twitching real fast while it reads like that? If it's just the bouncing up and down it may very well be the sending unit.
As much as I hate being one of those people... do a search on the forum and you will find oodles of posts regarding the messed up fuel gauge. Depending on what year your vehicle is.. (it looks to be around.. '99?) you can bring your vehicle into GM for a recall. I think it's 03-06 for the recalls.
But welcome to the world of bad GM clusters if you got a twitchin' gauge!
I've never saw a gauge go bad in the 20 years plus working on cars. Replace the sending unit.

well then i should have sent you mine, it fluttered like a hummingbird wing, replaced the cluster and no problems since 04

if it's not the cluster, the ground for the tank may be messed up. That'll cause an inaccurate or swinging gauge.

I have the exact same problem. When I put it in neutral the gauge goes all over the place, the needle only moves between beyond full and half a tank the for the entire tank of gas (found that out the hard way) and it flutters. Basically I have all the problems mentioned in every post.![]()
