Fuel gauge is whack (replaced fuel level sensor)

Anyone have any idea what might be wrong?

My fuel gauge will randomly drop to empty, sit there for a while, then jump up to full tank and sit there for a while. Then eventually fall back to the actual fuel level... I thought for sure it was a faulty fuel level float sensor. Replaced it with a brand new one and it's still doing the same thing.

You have two fuel level sensors. One on the pump side and one on the driver's side. You might see if the one you didn't replace is OK. Ohm test in Bentley gives you the values you should see empty and full. 10 ohms empty for each side and 250 ohms full each side Bentley page 160-5...

I have this same problem. It's highly annoying.

I replaced the one that is just a level sensor (driver side). It looks like the fuel pump is on the passenger side and it's a $330 part. Could it be that I really need to replace that whole thing just so my fuel gauge display's properly?

Did you do the ohm test as I suggested? No point in throwing parts at this if the ohm ranges are within spec.
Do the ohm test and tell us what you get...
