If it's below the bottom mark, the gauge is broken mechanically. In cluster...

I have a similar problem, only mine sorta works. When I fill up it goes to quarter tank insted of just over full like it used to. So I figured it was a quarter tank off but when it gets to E I get nervous and fill it and it takes ~13 gallons. The gas light'll come on occasionally.

What do you think, tank floater, gauge or sending unit?

[not to hijack your thread but it seems like they figured yours out ]

I did somethign similar when taking a U-turn the "fun" way.
The gas guage just dropped and stayed there. Once I got home I pulled the pump out and put it back in and it was fine. I think it got snagged on something.

I searched on this before. Bad sender (in fuel tank), wires/connector (corred and/or loose), or gauge. A bad sender makes sit drop to E at a certain point. Bad wires and/or connectors keeps it from going all the way to F. Mine has a bad sender and it suddenly drops to a little below E whenever I have less than 3/4 of a tank.

I'd guess either a disconnected/loose connector or, if it really is way below E, maybe it is the gauge mechanics.
