I recently re-installed my 1" 4crawler body lift and after about a day, the fuel gauge failed to drop any even after I drove it close to 50 miles. I am not familiar with any of the sensors for the fuel tank so I'm not sure where to look if theres a line connected to a sensor that might have gotten pulled when I lifted the body up.

Has anyone else out there with a body lift experienced this before and if so, what did you do to fix the problem??

 

I have reset the ECU and i've pulled the fuse for the gauge cluster.. all of that is fine. But it's still not working correctly. It says I have over a full tank when I really probably have 1/4.

 

You might check the sender wiring, usually towards the rear of the tank, to make sure it was not pulled apart when the truck was lifted to install the body lift. You may have pulled the connector apart during the lift. With the lift, there should be room to peek in between the body/floor and the top of the tank.

Thanks Roger, I probably should've done that before but we've had nasty weather here recently and haven't had a chance to get under it. I'll leave a follow up once I take a look at the wires.
