i just put 30$ of gas in my truck, and the guage remained on empty and the light said low fuel..... eventually as i kept riding the gauge crept up to a quarter, and then stopped... i know that 30$ is a bit more than a quarter, about a quarter and a half.... so i was wondering what the hecks goin on here? is it the computer, or is it the thing in the tank? suggestions or info appreciated...

 

Honestly no idea - but $30 in my '05 (same tank) is exactly like you said, about 3/8 a tank. If it's an '07 give your local dealer a call!

 

If you let the gas get down to near empty, the guage can do wierd things the next time you gas up. Make sure the gas cap is on tight. I would just keep an eye on it and if it doesn't clear up, get it checked out.

 

Did you leave the truck running when fueling?

 

+1.. This could be caused by the Anti-Slosh module (mot sure if the F150 calls it that or not) but this will happen if you leave most newer vehicles running while refueling

 

my 1999 F150 did that. but my 2004 doesn't.
