2006 Jeep Liberty help

turns out the problem is the fuel sending unit inside the gas tank.  dealer wanted 970.00 bucks to fix it  , i found the part online for 70 just gotta drop the tank and swap it out.

Dealer will only offer you a complete fuel pump module. What you got for $70 is probably a level sender. You'll have to take the pump module apart and replace  the sender. Do yourself a favor and keep driving it till its almost out of gas. Let us know how it goes.

Ditto on the driving 'til it's almost empty.  I had to drop the fuel tank out of my '90 Bronco II about 4 times, and draining the gas out of a tank is a PITA!
You get good at it after a while...

Never hurts to try Techron additive.  Ford had a TSB a few years ago about inaccurate and erratic fuel readings, their first recommendation was to add Techron and run a tank through it.
