The fuel pump sending unit is most likely the cause. The system needs a steady signal from the sending unit in the fuel tank to keep the needle from jumping around. I recommend seeking out a professional mechanic, such as one from YourMechanic, to come and test your vehicle for you. They can also replace the fuel gauge sender if this is verified to be the problem.
