Answers :

Sounds like you need new fuel pump. fuel pump located in gas tank. before you go buy a new fuel pump first push up and down on trunk of car real hard to try to dislodge the little armature inside of tank. this little armature is what sends the signal to the gauge telling you the quantity. push up and down on truck to try to dislodge small signal armature then check your quantity. try this when you are having the problem and i am willing to bet the little armature is stuck. the only way to fix is to buy a new pump.
