gas gauge reads more than full

[DrkHilndGreen]

Hey guys,

So I thought I had a bad sending unit since I would fill her up with gas (1991 GT hatchback) and the needle would go PAST full about 1.5 "notches."

I was fueling up a lot just to make sure I didn't run out without knowing it, anyway, for science, I threw a couple gallons in a gas can and decided to see how far she would go. She made it almost all the way to empty on the gauge before I decided to call it and just fill it up which ended up being about 11 gallons.

Do you guys observe the same thing? Or do I just have a quirky gas gauge?

Thanks,
JR

yea mine goes a little past full

mine goes about a needle width past full. but i ran out once and the needle wasnt even touching the red line on empty

Yeah, the needle goes past full, but doesn't read right near empty. So fill that thing up at like a 1/8th tank.

My needle will not only go past full, but so high to the point where you cant see it in the cluster. Once you drive it for a little it settles in and reads close to the right amount. The factory water temp will go haywire sometimes bouncing up and down lightning fast, good thing I have an aftermarket one lol.

HAHAHA my gas gauge does that same thing. every now and then i will look down and u cant even see the needle anymore. but it always goes back down after a couple minutes.

Service tech at 32 ford said one hot wire feeds the whole cluster.

I think pretty much every car i've ever driven long enough to fill the tank went over the F line.

hell who has the money to fill up to the f line with gas prices where they are?
