Gas guage issues

[justinspicher]

So I have filled up my ST twice now and I only get my gauge to read 3/4 full. I know it is filled but I won't read it correctly. Any suggestions?

My '04 is the opposite; I've never seen the low fuel indicator and get 160 kilometers before the gauge lowers to the full mark. I believe its just the nature of the beast. I had a problem with some wiring which made the gauge not work at all. While searching for solutions, I swear I found a way to sort of "reset" the gauge, but for the life of me, can't find it now. Other than bending the signal arm in the tank, I think we are out of luck!

Our trucks are funny that way. If you filled teh tank with the truck running the sending unit/ computer needs to reset itself next time you start your truck. I honestly wouldn't worry about it too much, just keep an eye on the gauge.

I filled it up last night and it was just fine. Crazy.

Your sending unit is going bad. I haven't had it happen, but a good friend had it happen to his truck. Easy fix but a pain in the butt to get to. Got to either take off the bed or drop the fuel tank.

What Rebel said is true, mine also floats around. Bad slosh module I guess, but I'll live with it for now. Level sender could be going bad, could be a broken wire on the winding.

Oh, on a Sport Trac removing the bed wo't get you anywhere. Only way to access it is to drop the tank.

Mine on 98 reads fine unless i almost run the tank empty then it usualy takes a few starts to come off of empty

Thanks, wasn't aware of that on the Tracs. I'm used to helping friends work on their full size trucks that keep breaking down :

you may want to run a bottle or two of seafoam through the tank, my gauge responded better after seafoam. The seafoam was to clean up the injectors, but the side effect was the gauge worked better. ( http://www.seafoamsales.com/ )

sticky gas gauge

I have used Chevron techron concentrate fuel system cleaner on various ford vehicles for that issue. i'ts some sort of sulfur build up on the sending unit contact wiper that causes that or something like that, a bottle of that techron on a fill up did the trick, my moutaineer needed two fill ups with that stuff o.k. after that.
