After looking it up on rockauto I see that it's around $130 just for the sensor/sending unit. Maybe because my car's a '97 GT? Who knows, but I may as well buy the whole pump for what I'll have to pay for just the sending unit...ugh...lol.

my mistake. i have a 01 GP and it's $25.00 so i assumed it was the same for all the 97-03 GP's. you can try going with a used sensor or pump from ed morad parts. they're very good people to deal with. they might have just the sensor they can sell you...Originally Posted by 97GTzbban1

No problem, I was assuming the same thing till I started shopping around for different parts for a '97. Actually I'm on a first name basis with Erik at Ed Morad's because of all the odds and ends parts I've been getting from them. They are great to work with! He did quote me $100 for a used pump (I didn't ask about just the sending unit, but I will), but I'm just thinking I'll keep doing what I've been doing as far as keeping track of fuel level by the trip odometer and just replace the whole pump when this one finally takes a crap.

a tip for keeping your fuel pump healthy, especially on fuel injected cars is to not let your gas level in your tank get below one quarter full. it's hard on your pump as your pump needs some fuel to keep it cool and also it won't suck up all the water and debris that's on the bottom of all tanks. hope this helps....No problem, I was assuming the same thing till I started shopping around for different parts for a '97.

I had this exact same problem. I too thought that the sending unit was bad. Luckily, before I purchased a new sending unit I decided remove the fuel pump. When I got into it I found that fuel pump o-ring had been replaced by someone who didn't know what they were doing. The o-ring had fallen out of place and was holding the float down making my gauge read empty. After, replacing the o-ring the right way the check engine light went away and my fuel gauge worked.
However, if your gauge is reading full all the time then it is probably the sending unit.
You can test if it is the fuel pump o-ring like mine was by simply filling the tank. If you notice that fuel leaks out just before the gas pump clicks off you have a bad o-ring not a bad sending unit.
If it is not your o-ring it still may not be the sending unit. On the float arm there are metal contacts that tell the computer how much gas is left in the tank. Sometimes these can get corroded. If this is the case simply clean it with a pink eraser.
Hope this helps you.

Good info....mine doesn't leak...pretty sure it's the sending unit, but am not planning to replace it till the pump actually goes. If it ain't broke, don't fix it...lol...but all I do is hit the trip reset and go about 300 miles and fill up, repeat procedure....Will have a new one lined up, ready to go when that time comes. Thanks for the info!

Glad to help.

i did mine about a month ago. $30.00 for the fuel level sensor (that's what it's called) through rockauto. on a 97 it's about $120.00 though. it takes 2 people to put the locking ring back on. also the new sensor comes with a new fuel pump gasket..Good info....mine doesn't leak...pretty sure it's the sending unit, but am not planning to replace it till the pump actually goes.

Thank for the info, to tell you exactly what mine is doing. It says its full then as your driving it will dramatically drop to empty and sit there for a bit and it may float up to either half or else it will read that it is completely full again. And this happened like 2 years ago but it resolved itself since I was to lazy to fix and since I knew how far I could go on a full tank I wasn't to concerned about running out of fuel.
