FUEL GAUGE STICKS ON 3/4
Some vehicles with extra capacity fuel tanks (23.5 gallons), built prior to VIN XXXXXXXXXGT202699, may have a fuel gauge that won't go over 3/4
with a full tank.
The fuel sender float may be contacting the fill tube causing the float to stick or restrict the float from traveling upward.
Service correction involves repositioning the float on the fuel tank sending unit.
