Fuel gauge issue

[codyryan07]

Started a trip the other day and after driving about 30 mins my fuel gauge bottomed out from full to below empty. Light chimed and everything. Started the truck a couple different times throughout the next few days, and would jump all the way to full then a few minutes later would bottom out again. I've searched and searched but found nothing really helpful. Any ideas? As of right now its reading fairly accurate (I believe) but want to make sure before i'm stranded somewhere. Any help is highly appreciated. Thanks.

Sounds like the sending unit is possibly going out. When you turn off the key and turn it on it moves from E to F that is to check the gauges.

Turns out the clip on the connection above the gas tank had broken and the plug was loose.. its reading accurate now and been about 75 miles. Hope that's all it was. Any idea where to get a new sending unit other than the stealership? Just in case its more than a simple fix? Thanks

Well if you found a loose wire harness I would just fix that. You may have to buy the pigtail from the stealership unless you go to the junk yard and find one. a little cut and splice will work but make sure you use heat shrink over the butt connectors to keep the connection from getting wet.
You can get the sending units from any part store they may have to order them because it will be a whole assembly.
