Gas Gauge Doesn't Work-Where to Start?

[buzz]

2000 XLT, 4.0. Gas gauge is wildy inaccurate and does not move much from the 1/4 spot. It bounces around while driving up/down hill. Ran our of gas with it showing 1/4 tank, no gas light on. Any ideas where to start? Gauge? Sending unit?

most likely the sending unit is worn out. you'll need to drop the tank and remove the old pump/sender assembly and replace it. i just replaced the pump on my '00 Mountaineer. not that hard to do on a rust free truck. PM me if you'd like instructions on how to do it.

Thanks. Truck is rust free for sure. Is the pump/sending unit all one piece?

more or less. the pump can be replaced separately, but the part you need will include a new pump installed.
