Disconnect the brown sending unit wire from the the fuse panel and measure the resistance. The ohm reading should be between 0 and 90 ohms, (0 being empty, 90 being full). If the reading is over approximately 90 ohms then the problem is probably in the sending unit or wiring. If the reading is for example 45 ohms and the dash gauge reading is well over 1/2 tank then the problem is in the dash gauge, (the resistor on the gauge, the needle has been removed and reinstalled in the wrong location, or the gauge itself is bad).
