Fuel Gauge

The fuel gauge indicates the approximate fuel level in the fuel tank.

The fuel gauge is regulated by a variable ground signal supplied:

to combination meter terminal 30 (without tachometer), or 44 (QG18DE with tachometer), or 21 (QR25DE) for the fuel gauge.
from terminal 2 of the fuel level sensor until and fuel pump
through terminal 5 of the fuel level sensor until and fuel pump, and
through body grounds B19 and B13.
