Fuel gauge fluctuates while driving
So the gas gauge on my GS400 will move almost a 1/8 way in either direction when I drive for a total of 1/4 of the fuel gauge so I have no clue where the gauge is actually reading. The gauge seems to move when going over hills, stopping, and accelerating. Once I'm on flat ground cruising or at a stop on flat ground it will take a couple seconds then settle in one spot.
Has anyone else had this problem and know what part to replace? Or if there is a fix for the current part?

You could replace the sending unit. Its just the part of the fue punp assemble that uses a float to measure the due level. The fuel punp aasembly is pretty easy to remove, then you could inspect the floqt and semdinf unit, and replace the culprit.
