Well either the wiring is screwed up or the sending unit is toast.

Fire Ranger is right , your not suppose to let the tank go less than half empty this fights corrosion and keeps the pump cool . Yes thats right folks you run your car or truck near E all the time your burning your pump out early . The gas keeps the pump cool and keeps the seals from drying out . Let it stand with no gas it and it corrodes and drys out. Thats right it has metal parts too.

my tuck has the same problem sometimes the gauge reads the right amount but other times its stuck above a full tamk i hooked a computer up and it threw a code for a fuel sensor which involves dropping the tank and could get kind expensive if the check engine light is on that is probably ur problem good luck.

1/2 a tank is a BS old wives tale. Running it dry is bad for the pump for those reasons. But 1/2 a tank is non-sense.

Yeah unfortunately the only way to fix it is to take the tank out. Sucks.

I was near empty yesterday and put in $20 today. Last night and today the gauge has not gone back up to past full. Even from all my stops thru the day.

Slightly off topic but is the fuel pump submerged down into the reservoir or just the pick up tube/screen?

I basically have the same problems with my gas gauge and Im leaning more towards the corroded wires at the top of the tank because I also have a problem with the rest of my gauges sticking when I turn off the ignition.
Im thinking they share the same ground behind the gauge cluster in the dash panel? Im not sure about this but it does make sense.
I plan to siphon my gas tank out tomorrow and see if it has any effect?
If it does I will post back with my findings.

I agree, but you shouldn't let it get below 1/4. I had a fuel pump burn out for that same reason, not because of me, but the PO was an idiot! I tell people that it's just like running a garbage disposer w/out water, it needs it to stay cool.

Fuel injected engines require higher fuel pressures than the older vehicles with carbs. Because of the work the fuel pump has to do, it gets very hot. The manufacturers put the pumps into the tank so that the fuel in the tank keeps them cool. It is for this reason that you should not run your vehicle with less than 1/4 tank to 1/2 of fuel. Once the fuel level drops below that level, the pump is not submerged anymore, and it then has no way to dissipate the heat. This will lead to premature failure of the pump... Usually about an $800.00 repair.

Now unless your are a licenced mechanic shut up with your stupid wives tales they have no place in the Industry . Even my apprentices know better . And there first year !
