I've been told this condition is due to a faulty fuel sending unit.

Funny thing is, my '97 has been having inaccurate readings lately. Boy, I don't want to drop that damn fuel tank. I'm holding out until I need a whole new pump.

If you don't fix it, make darn sure you keep track of your mileage per tank so you don't run yourself out of gas!

Fuel level sensor is faulty. Mine started acting up at around 100K. You have to drop the tank to replace it. The AC Delco replacement is about $300. I also replaced the pump at the same time for preventative maintenance. The AC Delco pump is about $125.

Use the trip odometer in the mean time. I always planned on filling up when I hit 300 miles.

Mine works fine ('cept for the traditional "dropping like a rock" at 1/4 tank). I had mine stick once at full because I topped it off, after the next fill-up, it worked like normal again.

Guys...

It'* EASY to change. Simply suck that tank dry and when you hit the 300miles or X KM'*.. put a gallon in the car and do a bunch of little trips to burn it off.. Also leaning under and tapping it..you can get an idea how much is left.

When dry..it'* not even a full person job. I showed Pat and Pete how easy it really is on the parts car...and that had 8 or so gallons in it.

It is a one person job. The trickiest part is disconnecting the fuel lines from the pipes coming out of the tank.

Using a transmission jack is EXTREMELY helpful for this job.

Easy..don't do them there. Disconnect by the fuel filter. The other tubes..disconnect at the top by the filler..that way you don't spill excess gas when the tank is being moved around.

Or a regular floor jack and a piece of board.. enough to distribute the weight.. However..if you run it dry...it won't weight enough to need a jack. (I tested this)
