Fuel gage

Does anyone know why my 90SC fuel gage goes all the way to the right and the gage light comes on? Sometimes when fuel is put in it'll work ok for awhile but has always read about 1/4 tank more than what is actually in the tank.
 
Mine does it too, it will swing FARRR right, almost horizontal.
Then doesnt want to ready correctly......Reads EMPTY and check gauge light comes on with 6 gallons left...

Ive tried cleaning grounds, changing gauges, changing ANTI SLOSH module.

Everything Minus dropping the tank
 
anti slosh module

I'm kind of thinking maybe the sender? Never checked anti slosh, where is it?

I'm also not in a big rush to drop tank, but hopefully this year I can put in the later model tank and get a decent set of pipes on, then I'll put new pump and sender in. If that solves the problem I'll post it. Thanks for info.
 
I dropped my tank and switched to the late model tank for my new exhaust. It's not very hard at all, the hardest part about dropping the tank on our cars is you have to cut off the exhaust under it. Not a big deal if you are redoing the exhaust like I was, but it really sucks if you have no plans of a new exhaust.
